FAssets

FAssets bring assets from chains without smart contracts — Bitcoin, XRP, Dogecoin — onto Flare as ERC-20 tokens (FBTC, FXRP, FDOGE), trustlessly and over-collateralised.

How it stays trustless

FAssets combines two enshrined protocols: the FDC proves the underlying payment happened, and the FTSO prices the collateral.Agents hold the underlying asset and post FLR/stablecoin collateral well above the value they back; if an agent misbehaves or under-collateralises, it's liquidated and users are made whole.

Minting and redeeming

1. Reserve a minting slot with an agent (pay a small fee).
2. Send the underlying asset (e.g. XRP) to the agent with the payment reference.
3. The FDC verifies the payment; you call executeMinting and receive the FAsset.
4. Redeem by burning the FAsset; the agent pays you the underlying back on its native chain.

Participants: users mint/redeem, agents provide backing, collateral providers earn a share of fees, and liquidators/challengers keep agents honest.
