"Soon after most transactions go fully feeless. Zero commission." — Pavel Durov, Founder, Telegram / TON
The Open Network (TON) reduced transaction fees sixfold on April 24, 2026, dropping the per-transaction cost to 0.00039 TON (~$0.0005), fixed regardless of network congestion. The move follows Catchain 2.0, a consensus-layer overhaul activated on April 9 that cut block times from 2.5 seconds to 400 milliseconds and increased throughput tenfold. Telegram founder Pavel Durov framed the fee reduction as Step 2 of a seven-step roadmap branded "MTONGA" (Make TON Great Again), with fully feeless transactions described as the next milestone.
The speed-and-fee restructuring carries a quantifiable cost. Because block rewards remain fixed at 1.7 TON per masterchain block and 1.0 TON per basechain block, the sixfold increase in block production mechanically raises TON's annualized inflation rate from approximately 0.6% to 3.6%, according to multiple technical analyses of the upgrade. A validator governance vote scheduled for June 2026 aims to re-calibrate rewards — potentially reducing the masterchain reward from 1.7 TON to 0.35 TON per block — but the outcome remains uncertain.
The juxtaposition is stark: TON trades at $1.37, down 83% from its June 2024 all-time high of $8.23, with a market cap of $3.4 billion against just $56.4 million in DeFi TVL according to DefiLlama. The network is betting that near-zero fees will unlock mass adoption through Telegram's 950-million-plus user base, but the economic model raises structural questions about long-term validator incentive sustainability.
TON's Catchain 2.0 upgrade represents a full revision of the Byzantine Fault Tolerant (BFT) consensus protocol that underpins the network. The upgrade went live on mainnet April 9, 2026, following a validator vote on April 8-9 and a phased validator rollout beginning April 7.
Key performance changes:
| Metric | Pre-Upgrade | Post-Upgrade | Change | |--------|------------|-------------|--------| | Block time | 2.5 seconds | ~400 ms | -84% | | Transaction finality | ~6 seconds | ~1 second | -83% | | Throughput | Baseline | 10x increase | +900% |
The technical implementation introduces the QUIC transport protocol — originally developed by Google for HTTP/3 — to accelerate inter-validator communication. Developers have been instructed to migrate to Streaming API v2, which delivers four sequential transaction statuses: pending, confirmed, finalized, and trace_invalidated.
The upgrade's impact on Telegram Mini Apps (TMAs) is immediate. Prior to Catchain 2.0, every on-chain action within a mini app required multi-second waits. According to KuCoin's technical analysis, the gap between user action and on-chain confirmation has "effectively collapsed," which matters for a platform claiming over 500 million monthly mini-app users as of late 2025.
Announced April 24, 2026, Step 2 of the MTONGA roadmap sets a fixed transaction fee of 0.00039 TON per transaction, equivalent to approximately $0.0005 at current prices. Two design decisions distinguish this from typical fee structures:
1. Fixed pricing. Unlike Ethereum's EIP-1559 dynamic base fee or Solana's localized fee markets, TON's new fee is invariant to network load. There are no congestion surcharges.
2. Fee distribution. Under TON's existing tokenomics, 50% of transaction fees are burned and 50% flow to validators. At $0.0005 per transaction and current daily volumes of approximately 2.16 million transactions, this implies:
For context, Solana generates approximately $50,000-$150,000 in daily fee revenue (excluding priority fees and MEV), and Ethereum's Layer 1 generates several million dollars daily. TON's fee revenue from organic transactions is, by design, negligible.
The stated endgame is more aggressive: Durov has indicated that "most transactions will soon become fully feeless," with zero commission for the majority of user actions. The mechanism for achieving this — whether through subsidized gas, fee abstraction, or direct protocol changes — has not been specified.
The speed improvement creates an unintended monetary expansion. Block rewards were set when blocks arrived every 2.5 seconds. At 400ms block times, the network produces roughly 6x more blocks per unit time, while per-block rewards remain unchanged.
Inflation arithmetic:
| Parameter | Value | |-----------|-------| | Masterchain block reward | 1.7 TON | | Basechain block reward | 1.0 TON | | Pre-Catchain 2.0 inflation | ~0.6% annually | | Post-Catchain 2.0 inflation | ~3.6% annually | | Circulating supply | ~2.5 billion TON | | Additional annual issuance at 3.6% | ~90 million TON |
At $1.37 per token, the increased issuance represents approximately $123 million in annual dilution — more than double TON's current DeFi TVL of $56.4 million.
The TON Foundation has acknowledged this imbalance. A validator governance vote, expected to conclude in June 2026, proposes reducing masterchain block rewards from 1.7 TON to 0.35 TON. If enacted, this would bring inflation closer to pre-upgrade levels while preserving the speed gains. However, the vote requires validator consensus, and validators currently benefit from the elevated rewards — creating a potential misalignment of incentives.
The 50% fee-burn mechanism, which was meaningful at higher fee levels, becomes economically immaterial at $0.0005 per transaction. At current volumes, the annual burn from transaction fees amounts to roughly $197,000 — a rounding error against $123 million in new issuance.
The L1 fee landscape in April 2026 spans four orders of magnitude:
| Network | Avg. Fee per Tx | Fee Model | Daily Txs (approx.) | Notes | |---------|----------------|-----------|---------------------|-------| | TON | $0.0005 | Fixed | ~2.16M | Post-MTONGA Step 2 | | Solana | $0.00025 | Dynamic (localized) | ~50-80M | Priority fees extra | | Base (L2) | $0.01-$0.10 | EIP-4844 blobs | ~5-10M | Post-Pectra reduction | | Ethereum L1 | $0.50-$3.00 | EIP-1559 dynamic | ~1.1M | Spikes to $15-$30 |
Solana remains cheaper per transaction than TON even after the fee cut. The difference is that Solana's fee model includes localized fee markets and priority fees that add revenue during congestion, plus a substantial MEV extraction layer. TON's fixed-fee model eliminates this variable revenue.
The sustainability question for each network differs:
None of these L1 networks are fee-revenue self-sustaining. But TON's fee-to-subsidy ratio, at roughly 0.3%, is the most extreme among major chains.
TON's user funnel is unusual in crypto: it flows from a centralized messaging app (Telegram, 950M+ users) into on-chain activity, rather than the reverse.
Key network statistics (April 2026):
| Metric | Value | Source | |--------|-------|--------| | Total accounts | 162 million | Tonscan | | Monthly active wallets | ~1.78 million | TonStat | | Daily on-chain transactions | ~2.16 million | TonStat | | Daily wallet activations | ~43,623 | TonStat | | DeFi TVL | $56.4 million | DefiLlama | | Market cap | $3.4 billion | CoinGecko | | TON price | $1.37 | CoinGecko | | Price vs. ATH ($8.23, Jun 2024) | -83% | CoinMarketCap |
The ratio of total accounts (162M) to monthly active wallets (1.78M) implies an activation rate of approximately 1.1%. First-time user transactions reportedly constitute 38% of total demand, according to TonStat data, suggesting ongoing onboarding but limited retention.
DeFi TVL of $56.4 million against a $3.4 billion market cap yields a TVL-to-mcap ratio of 1.7% — significantly below Ethereum (~15-20%), Solana (~5-8%), or Arbitrum (~8-12%). This indicates that despite high account numbers, meaningful on-chain capital deployment remains limited.
The weekly active transactions figure of 3.8 million represents a 32% increase, and fee revenue spiked 52% — but this follows the Catchain 2.0 activation and may reflect upgrade-driven activity rather than organic growth.
TON's trajectory toward feeless transactions invites comparison with two prior attempts.
IOTA operated a feeless model for IoT microtransactions from its 2016 launch through 2025. The model relied on a Directed Acyclic Graph (Tangle) where users validated two prior transactions as their fee equivalent. In practice, the network suffered from centralization (the Coordinator node), spam vulnerability, and inability to sustain a validator economy. In 2025-2026, IOTA Rebased abandoned the feeless model, introducing gas-based transaction fees to "discourage spam, incentivize validators and delegators, and maintain economic integrity," according to IOTA's documentation. The foundation acknowledged this "represents a significant departure from the original IoT-friendly vision."
Nano maintained a fully feeless architecture through Open Representative Voting, where validators operate at their own cost. This produced a network with near-zero adoption outside a niche community, limited protocol development funding, and no economic mechanism to scale validator infrastructure with demand.
The pattern is consistent: feeless models struggle to sustain validator economics at scale. TON's approach differs in that it retains nominal fees (currently $0.0005) while aspirationally targeting zero fees for "most" transactions. The critical variable is whether Telegram's distribution advantage can generate sufficient non-fee revenue — through ads, premium subscriptions, or ecosystem value capture — to subsidize on-chain operations indefinitely.
Durov has outlined seven steps for the MTONGA roadmap, of which two are now live:
| Step | Description | Status | |------|-------------|--------| | 1 | Speed: Catchain 2.0 (400ms blocks) | Live (Apr 9) | | 2 | Fees: 6x reduction to $0.0005 | Live (Apr 24) | | 3 | TON Teleport: Trustless BTC/ETH bridge | Announced | | 4-7 | Not yet disclosed | Unknown |
The TON Teleport bridge, described as Step 3, would operate at sub-second speeds enabled by Catchain 2.0 and aims to bring Bitcoin and Ethereum liquidity onto TON. According to Phemex's analysis, "by the end of 2026, the vision is to have Telegram act as the primary interface for the entire crypto world."
No timeline has been provided for Steps 3-7. The remaining roadmap items have not been publicly detailed.
TON cut transaction fees 6x to $0.0005 (fixed) on April 24, following Catchain 2.0's 10x throughput improvement on April 9. Feeless transactions are the stated next goal.
Inflation jumped from 0.6% to 3.6% annually as a mechanical side effect of faster block production with unchanged rewards. A June 2026 validator vote may reduce masterchain rewards from 1.7 to 0.35 TON per block — but validator approval is not guaranteed.
Fee revenue is structurally negligible. At current volumes and pricing, TON generates under $400,000 in annual fees against ~$123 million in new token issuance. The fee-to-subsidy ratio of 0.3% is the lowest among major L1 networks.
162 million accounts mask limited active usage. Monthly active wallets total 1.78 million (1.1% activation). DeFi TVL of $56.4 million represents 1.7% of market cap.
Prior feeless models failed. IOTA abandoned feeless architecture in 2025-2026 after years of centralization and spam issues. Nano's feeless model produced near-zero ecosystem growth.
The bet is distribution, not fee economics. TON's thesis depends on Telegram's 950M+ user base generating sufficient network effects to sustain value without traditional fee revenue — a model untested at this scale.
TON's fee reduction and the MTONGA roadmap represent a deliberate wager: sacrifice fee revenue to eliminate friction for Telegram's massive user base, then capture value through network effects and ecosystem growth. The technical execution of Catchain 2.0 is demonstrably sound — 400ms block times and sub-second finality are competitive with or superior to any L1 in production.
The economic execution is less certain. The 6x inflation increase is a real cost borne by existing token holders, and the governance mechanism to correct it requires validators to vote against their own short-term interest. The path to feeless transactions raises unresolved questions: who pays validators when fees reach zero, how is spam prevented without economic cost, and what happens to network security if staking rewards are compressed.
The precedent from IOTA and Nano suggests that feeless models converge toward either re-introducing fees or accepting permanently limited ecosystems. TON's differentiator — Telegram's distribution — is genuine but unproven as a blockchain business model. The network has 162 million accounts but $56.4 million in TVL, suggesting that distribution and economic engagement are, for now, different things.
The data does not support a conclusion in either direction. What it shows is a network trading long-term economic sustainability questions for short-term user acquisition. Whether Telegram's user base converts that acquisition into self-sustaining on-chain economic activity will determine if MTONGA is a viable growth strategy or an expensive subsidy program.
