Sonic's V2.2 Update Lets Apps Cover Gas Fees on Behalf of Users, No Relayer Required
Sonic Labs detailed plans for version 2.2 of its network protocol on September 3, 2026, introducing two new transaction sponsorship modes that allow decentralized applications to pay gas fees on behalf of their users without relying on third-party relay infrastructure.
The update addresses a persistent onboarding problem common to every blockchain: users who receive stablecoins or other tokens on a new network often cannot interact with any application until they separately acquire the network's native gas token. On Sonic, that token is S. V2.2 gives developers a protocol-native way to absorb that cost themselves.
How the New Sponsorship Modes Work
V2.2 adds two distinct modes to a sponsorship framework Sonic first introduced in version 2.1.2, released October 8, 2025. The first mode is full network sponsorship, where qualifying transactions carry zero cost to the end user, with gas covered by funds held in an on-chain contract called the Subsidies Registry. The second is "successful-only" sponsorship, where a developer's budget is charged only when a transaction actually completes. Failed transactions do not drain the sponsor's balance.
Developers can configure sponsorship with considerable specificity. The targeting options include individual smart contracts, specific functions within those contracts, a specific function within a specific contract (targeting both simultaneously), ERC-20 token approvals, and first-time interactions from brand-new wallets. That last option, sometimes called "bootstrap" sponsorship, removes the onboarding cliff where new users abandon a product at the first transaction prompt.
The architecture separates Sonic from how most Ethereum-based networks handle the same problem. Ethereum's account abstraction standard, ERC-4337, routes sponsored transactions through off-chain bundlers, a separate EntryPoint contract, and a paymaster contract that works in conjunction with that EntryPoint to cover gas costs. Sonic processes sponsorship requests inside the node itself, with the Subsidies Registry holding deposited S tokens on-chain and defining which transactions qualify. There is no off-chain relay service in the stack. As Sonic Labs stated in the announcement: "Sponsorship changes who pays for execution, not who authorises the action." The company has also framed the broader design philosophy plainly: "Sponsorship shouldn't be infrastructure every team rebuilds." Users retain full authorization over their transactions; the change is purely in how the fee routes.
For technically sophisticated readers, it is worth noting that EIP-7702, introduced with Ethereum's Pectra upgrade in May 2025, represents a third architectural approach in this space. It allows existing externally owned accounts to temporarily delegate execution to a smart contract without a full account migration, a design distinct from both ERC-4337 and Sonic's protocol-native model.
On-Chain Context
Sonic launched in January 2025 as the rebrand of the Fantom blockchain, with S replacing FTM at a one-to-one ratio. The network claims 400,000 transactions per second and sub-second finality via its Lachesis Asynchronous Byzantine Fault Tolerant (ABFT) consensus mechanism, with average gas fees below $0.01. S currently trades at roughly $0.027, approximately 97% below its all-time high of $1.03. Market capitalization sits between $76 million and $106 million depending on the data source, with about 2.88 billion S in circulation out of a 3.22 billion total supply.
Total value locked on Sonic stands at approximately $16.1 million as of this writing, according to DefiLlama. That figure represents a decline of more than 98% from the network's peak TVL of around $1.1 billion in May 2025. Sonic's FeeM program, which rebates 90% of network fees to the developers generating them, has distributed more than 2.6 million S tokens to builders since the network's January 2025 launch.
Why This Matters Outside the US
The practical stakes of gas sponsorship are highest in high-volume remittance corridors across South Asia and sub-Saharan Africa. A user in Lagos or Dhaka who receives USDC.e bridged from a diaspora sender abroad has no straightforward path to acquiring S before executing that first transfer or swap. Every additional step in that process is a dropout risk. Under V2.2, a developer building a remittance or savings product can sponsor those initial interactions at the protocol level, without custom relayer infrastructure. It should be noted that Sonic has not announced India- or Africa-specific partnerships or go-to-market activity tied to these features. The regional case for V2.2 rests on structural fit rather than any announced deployment strategy.
Gas fees and the requirement to hold native gas tokens have been identified as the two biggest historical barriers to Web3 payments adoption in emerging markets, according to Fuse.io. With approximately 1.4 billion unbanked adults globally, the scale of the potential audience for frictionless stablecoin access is substantial. Stablecoin transaction volumes globally grew 91% year-over-year in 2025 to an adjusted $10.9 trillion, according to Bessemer Venture Partners. Real-world stablecoin payment volumes reached roughly $400 billion, with 60% in business-to-business flows. Users arriving via fiat-to-stablecoin on-ramps, rather than through crypto-native channels, represent the demographic that gains the most from removing the gas cold-start requirement.
Competing networks with emerging-market focus, including Celo, Stellar, and NEAR, already support various forms of gas abstraction. Celo and Stellar allow gas fees paid directly in stablecoins, while NEAR uses meta-transactions to achieve a similar effect. Sonic's approach differs in that sponsorship is handled at the protocol layer rather than through an application wrapper. That design reduces reliance on external relay services and the trust assumptions that come with them. In regulatory environments such as India's RBI-supervised fintech sector, where the custody and routing of funds face additional scrutiny, minimizing off-chain infrastructure intermediaries carries practical weight.
What Comes Next
V2.2 also bundles transaction batching, pre-execution checks, and expanded smart contract capacity. Sonic has not announced regional partnerships tied to the sponsorship features. The real-world impact will depend on developer adoption and on whether the ecosystem recovers from its current low-activity period. Sonic's FeeM rebate structure is also under review for a potential shift to a tiered model, which could narrow the indirect subsidy for app-level sponsorship budgets. Taken together, Sonic's recent upgrade sequence, including Pectra alignment and the move to protocol-native gas sponsorship, suggests a sustained focus on developer-facing infrastructure rather than a single isolated product release.
