bridge(), send(), swap(), unifiedBalance(). Eight stablecoins. Four chains. Every call returns a real Ed25519-signed Hive receipt, verifiable offline. Write your code against Hive today; rebind to Circle Arc when it ships. Same interface, broader surface.

Every bridge, send, swap returns a sequence-numbered, Ed25519-signed receipt that any party can verify offline using the public key at /v1/receipts/pubkey. No archive node. No block explorer. No trust in us.
The receipt itself is the evidence artifact. Drop it into a compliance pipeline and the auditor verifies the chain of custody without needing access to your infrastructure.
Move regulated dollars through Aleo with USDCx (Circle) or USAD (Paxos) in v0.2. Zero-knowledge settlement with the same call surface.
Flat fees in USDC: send $0.001, swap $0.02, bridge $0.05. Published. Inspectable on every quote.
