Brale launches ION Protocol to eliminate capital bottleneck in multi-chain stablecoin scaling

Brale, a stablecoin infrastructure firm, has introduced ION Protocol on testnet, an interoperability system that moves tokens between blockchains by burning them on the source chain and minting an equivalent amount on the destination chain. The approach sidesteps the need for pre-funded liquidity pools on every supported network, which Brale founder and chief executive Ben Milne describes as the primary barrier to scaling bespoke stablecoins at industry volume.

The context matters: CoinGecko tracks more than 350 stablecoins against a market capitalisation exceeding $300 billion, and the issuer base is broadening beyond Tether and Circle Internet to include banks, fintechs, asset managers, and crypto-native firms. Brale itself supports over a hundred stablecoin programmes across more than 30 blockchains, with many customers processing billions of dollars in monthly payment volume while holding relatively modest token balances. As issuance multiplies, the capital required to maintain liquidity pools across every chain-token combination grows combinatorially, and Milne’s view is that no realistic capital base resolves that arithmetic.

ION applies a burn-and-mint mechanism similar to Circle Internet’s Cross-Chain Transfer Protocol (CCTP), but extends the model to any participating issuer rather than a single token. Launch partners on testnet include Monad, Rain, Coinflow, Turnkey, Etherfuse, Spark, and Canton, with a broader rollout to follow. The design appears aimed squarely at the cohort of institutional and fintech issuers whose custom stablecoins are transaction-oriented rather than investment instruments, making capital efficiency a more pressing constraint than it is for reserve-heavy issuers.
