H081 Capital

Returns the stream_loan market read from Solana mainnet: the registry, every loan slot (lender, asset, principal, repaid, expiry, pledge, stream bounds, settlement, shortfall as of chain time), open slots waiting for a borrower, counts and the origination fee rate. Cached for 30 seconds. The H081 private bank is live on Solana mainnet, not audited yet; use at your own risk.

Proves a statement about a stipend_pool allowance (Groth16 disclose circuit): remaining at least, lifetime spend at most or window spend at most a bound, for an audience, as of a root the pool knows. Input: the allowance figures and policy (the prover sees them), its Merkle path, the bound and the audience; no spending key. Output: the proof, its public signals and the payload for verify_disclosure. The H081 private bank is live on Solana mainnet, not audited yet; use at your own risk.

Checks whether a stipend_pool operation (the same body as POST /v1/solana/relay) would be relayed, without sending anything: relay fee against the minimum and 0.20% rule, capacity_stake capacity, known root, unspent nullifiers, fresh timestamp, the accounts the final transaction needs and the transaction plan. Returns ok plus every refusal the relay API would answer with. The H081 private bank is live on Solana mainnet, not audited yet; use at your own risk.

Submits a stipend_pool operation (withdrawal, spend, grant or delegate; the same body as POST /v1/solana/relay) through a dedicated priority lane: its own in-flight capacity and a higher priority-fee cap on every transaction. The operation must still carry the in-proof relay fee to the treasury fee account. Returns the signature and compute units.
