Brale, a stablecoin infrastructure firm, is implementing a compatibility protocol designed to put an end to what it says is a bottleneck in the industry's development: moving the rapidly growing number of branded stablecoins across blockchains.
Called the ION protocol, it allows participating stablecoins to move between blockchains by burning tokens on one network and minting an equivalent amount on another. Unlike most blockchain bridges, this model does not require pre-funding liquidity pools in each supported blockchain.
The $300 billion stablecoin market is dominated by Tether (USDT) and Circle ($USDC), but new entrants are emerging. Banks, fintech companies, crypto firms, and asset managers are increasingly issuing their own branded tokens for payments, settlements, and tokenized assets.
Data provider CoinGecko already tracks over 350 coins pegged to a real-world asset like a fiat currency, highlighting the growing need for infrastructure to connect the increasingly fragmented ecosystem. Brale argues that today's interoperability model will not scale as more issuers introduce their own versions.
The Stablecoin Scaling Problem
"The company supports over 100 stablecoin programs across more than 30 blockchains", Brale founder and CEO Ben Milne reported.
Many of its clients process billions of dollars in monthly payments while maintaining relatively small stablecoin balances, as their tokens are designed for transactions, not investments.
Moving assets between blockchains typically relies on liquidity pools or wrapped tokens, which requires locking up capital in each supported network. As the number of stablecoins and blockchains grows, so does the capital requirement.
"Liquidity between stablecoin programs is barrier No. 1 to scaling individual stablecoins," Milne said. "There isn't enough capital in the world to solve this."
Due to insufficient capital to create deep liquidity pools for every stablecoin on every blockchain, the current model becomes unsustainable as issuance accelerates. Instead, ION employs a "burn and mint" approach, similar to issuer Circle's ($USDC) Cross-Chain Transfer Protocol (CCTP), extending the model to any participating stablecoin issuer, not just a single token.
The protocol is launching with partners including Monad, Rain, Coinflow, Turnkey, Etherfuse, Spark, and Canton, first on a testnet and then more broadly.
