Custodia and Vantage have proposed a new type of token that can toggle between bank deposits and stablecoins, aiming to bridge traditional finance and blockchain. The dual-purpose token could let users move funds seamlessly between conventional accounts and digital assets, potentially making payments and settlements faster. The two firms say the model could reshape how banks interact with crypto.
How the token would work
The proposed token exists on a blockchain but is designed to switch between two states. When in deposit mode, it represents a dollar held in a regulated bank account at Custodia. When toggled to stablecoin mode, it becomes a transferable digital asset that can move across crypto platforms. That flexibility means a user could hold funds as a bank deposit, then convert them on the fly to a stablecoin for a transaction, without leaving the same token.
This isn't just a wrapper or a bridge token. Custodia and Vantage have built the toggle feature into the token's smart contract, so the shift happens programmatically. The idea is to eliminate the friction of moving money between bank rails and blockchain rails.
If the model works at scale, it could change how banks handle settlement and payments. Instead of relying on slow wire transfers or multiple intermediaries, a bank could issue these dual-purpose tokens directly. The same token that sits in a customer's deposit account can be sent instantly on-chain as a stablecoin, then converted back to a deposit when it arrives.
That efficiency gain is the core pitch. Custodia and Vantage argue that integrating blockchain into the back end of banking could cut costs and speed up transactions.
The proposal lands at a time when traditional banks are still cautious about crypto. But the dual-purpose structure might address regulatory concerns: the deposit side stays within a regulated bank, while the stablecoin side operates on public blockchains. The two firms haven't announced a timeline for deployment or which regulator they'll need to satisfy first.
