Stablecoin firm Brale says new protocol can remove a major hurdle to scaling custom tokens

Brale, a stablecoin infrastructure firm, has introduced the ION Protocol, an interoperability system designed to facilitate the transfer of stablecoins across different blockchains. The protocol works by burning tokens on one chain and minting an equivalent amount on another, enabling seamless movement of participating stablecoins without relying on pre-funded liquidity pools. This approach contrasts with traditional blockchain bridges, which require capital to be locked up in liquidity pools on each supported network.

The announcement comes at a time when the stablecoin market is rapidly growing and becoming increasingly fragmented, with over 350 tokens tracked by CoinGecko and a total market capitalization exceeding $300 billion. While Tether’s USDT and Circle Internet’s USDC dominate the market, a growing number of banks, fintech companies, crypto firms, and asset managers are issuing their own stablecoins for various uses, such as payments and tokenized assets. Brale views the current interoperability model as insufficient to scale this expanding ecosystem.

Brale’s founder and CEO, Ben Milne, highlighted that many of Brale’s customers process billions of dollars in monthly payment volume but maintain relatively small stablecoin balances, as their tokens are transaction-focused rather than investment vehicles. The main challenge to scaling bespoke stablecoins, according to Milne, is the liquidity requirement for moving assets across multiple blockchains—an obstacle the ION Protocol seeks to address by eliminating the need for extensive capital reserves in liquidity pools. The protocol adopts a burn-and-mint mechanism similar to Circle’s Cross-Chain Transfer Protocol but extends this capability to any participating stablecoin issuer.

ION is currently launching on testnet with partners including Monad, Rain, Coinflow, Turnkey, Etherfuse, Spark, and Canton, with plans for a broader rollout. Brale argues that by reducing capital requirements and simplifying interoperability, the ION Protocol could remove a major hurdle to the wider adoption and scaling of custom, issuer-specific stablecoins in an increasingly fragmented market.
