How Stablebonds work across chains

How Stablebonds work across chains

Etherfuse uses a hub-and-spoke model — similar to the approach M0 uses to distribute a token across chains. Solana is the hub, and the other supported networks are spokes connected to it.

Solana is the hub

The core Stablebond logic — purchasing, redemption, and issuance — lives in the smart contract on Solana. This is where Stablebonds are issued and where the canonical supply lives.

Other chains are spokes, connected with a bridge

To make Stablebonds available on Stellar, Base, Polygon, and Monad, Etherfuse bridges them to and from the Solana hub using a cross-chain bridge such as LayerZero. A Stablebond is bridged out when it moves to another network and bridged back when it returns, keeping a single, consistent supply across every chain. Stablebonds are free to move between chains.

What this means for you

• On Solana, you interact with the hub contract directly — instant from prefunded liquidity, or a purchase order / weekly payout when needed (see How on-chain purchases & redemptions work and How on-chain purchases & redemptions work).

• On the spoke chains, you buy and redeem through market liquidity (for example, a USDC↔CETES market), which fills immediately when there is enough liquidity.

• One asset, many chains: the same Stablebond can move across supported networks while remaining backed by the same underlying bond.
