Brale launches ION to transfer custom stablecoins across chains

Brale introduced ION Protocol on July 29, 2026. The system moves custom stablecoins between blockchains by burning tokens on the source chain and minting equivalents on the destination chain after an attestation.

ION uses an attested burn-attest-mint process. Tokens are destroyed on the origin chain, an attestation confirms the burn, and the issuer authorizes minting on the destination chain. Brale reports total supply stays constant across chains.

The protocol removes the need for pre-funded liquidity pools on each network. Brale reports the technology behind ION has supported more than $10 billion in mint and burn activity on its platform.

Launch partners include Solana, Monad, Rain, Coinflow, Turnkey, Spark and Canton. Brale has published technical documentation on its blog and plans a testnet in the third quarter of 2026 for partners to begin integration, with broader availability planned later.

There are more than 350 stablecoins with a combined market value above $300 billion, and many issuers currently fund liquidity pools on every chain they support. Brale framed ION as a response to that fragmentation.

The model resembles the burn-and-mint method used by some large issuers. Circle’s Cross-Chain Transfer Protocol uses a similar approach for USDC; ION applies the same pattern to any participating stablecoin issuer.

Brale acknowledges the rollout is early. The attestation layer adds an additional trust surface that issuers, auditors and regulators may review during public testing. The company has scheduled the testnet for Q3 2026 so partners can assess the attestation mechanics and security assumptions.

Ben Milne, founder and chief executive of Brale, described ION as “saves the ecosystem tens of billions of dollars in liquidity obligations today and potentially trillions in the years ahead.”
