Solana Ships Native Payments Rail for Subscriptions and Allowances

The Solana Foundation has shipped a native onchain subscriptions and allowances primitive on Solana mainnet, giving any team building on the network a shared program for recurring billing, capped delegated spending, and merchant-published billing tiers without standing up its own custody, billing, or processor stack.

The Subscriptions Delegation Program, audited by Cantina, supports three authorization models in one open-source contract, the foundation said in a blog post Tuesday: a fixed allowance with a spending cap and optional expiry; a recurring delegation that lets a delegate pull up to a set amount per period; and a merchant subscription plan that publishes immutable billing terms users can subscribe to.

The program works with both SPL Token and Token-2022 mints and has been integration-tested with Squads multisig and Swig smart-wallet flows.

The move puts a payments-rail primitive directly into the protocol library on the third-largest chain by total value locked, alongside Ethereum at $40.35 billion and BSC at $5.44 billion, according to DefiLlama. Solana itself sits at $5.08 billion in TVL, with SOL trading at $75.02 and a market capitalization of $43.42 billion, per CoinGecko.

The recurring-payments stack it now competes with is far larger: Stripe processed $1.9 trillion in total payment volume in 2025 and is on a $5.84 billion net-revenue run rate, according to its 2025 annual letter, while Recurly, Chargebee, and the card networks' merchant rails collectively gate the recurring-revenue economy that the Solana program is designed to disintermediate.

Design Partners

Six design partners are already integrating the program. Helius, one of Solana's largest RPC and indexer infrastructure providers, is letting customers subscribe to API tiers directly onchain, replacing invoiced billing. Dynamic, a wallet-as-a-service provider used by enterprise integrators, is wiring the program into checkout flows alongside Fireblocks Flow, the agentic-payments suite the institutional custodian launched in May. Confirmo, a stablecoin payment gateway serving global SaaS and enterprise merchants, will use the recurring model to automate stablecoin invoice collection. The remaining three named integrators — Majority, Mesh, and Meow — span consumer banking, B2B payments, and stablecoin neobanking.

Prior onchain attempts at the same problem have stayed small. Superfluid, the per-second streaming protocol launched in 2020, holds $4.54 million in TVL across Optimism, Ethereum, and Base, per DefiLlama. Sablier, the original token-streaming protocol from 2019, holds $3.54 million in active protocol TVL, with a much larger but separate vesting-distribution surface. Neither has crossed into mainstream merchant billing — both remain narrow tools for payroll, vesting, and DAO contributor payouts.
