Contract 8110634bc9c8d95f0d852f0dd3fea6951a92140fb2b23c41fbced507a5125c9d

Atomic swap between USDM0 and USDM1 (port of EVM swapTokens).
Always requires a USDM1 price attestation (USDM0 is pegged at 1e7).
The signed swap permit binds the input token, output token, amount,
nonce, and validity window. The broker pulls input by allowance, burns
the broker-held input, and mints output in one transaction.

Redeem USDM for collateral via permit + price attestation.
Atomic redemption: consumes the permit, transfers collateral from the
beneficiary to the recipient, and burns USDM in one transaction.
Collateral movement is allowance-based because the beneficiary owns the
redemption pool outside the broker contract.

fn redeem(
    env: soroban_sdk::Env,
    source: soroban_sdk::Address,
    token_id: u32,
    amount: i128,
    collateral: soroban_sdk::Address,
    recipient: soroban_sdk::Address,
    collateral_price: PriceAttestation,
    usdm_price: PriceAttestation,
    permit: RedeemPermitAttestation,
)

fn get_redemption(
    env: soroban_sdk::Env,
    redemption_id: soroban_sdk::BytesN<16>,
) -> Option

Queue a redemption for manual processing.
The queued path uses the same redemption nonce lane as redeem,
escrows USDM in the contract, and records one pending redemption per
redeemer. Fee policy, whitelist policy, and redemption sizing are
enforced before the queue permit is signed.

fn queue_redemption(
    env: soroban_sdk::Env,
    source: soroban_sdk::Address,
    token_id: u32,
    amount: i128,
    collateral: soroban_sdk::Address,
    recipient: soroban_sdk::Address,
    collateral_price: PriceAttestation,
    usdm_price: PriceAttestation,
    permit: QueueRedemptionPermitAttestation,
)

Cancel a pending queued redemption and return escrowed USDM.
The redeemer can cancel their own pending redemption; the administrator
can also cancel it as an operational escape hatch.

fn cancel_redemption(
    env: soroban_sdk::Env,
    signer: soroban_sdk::Address,
    redemption_id: soroban_sdk::BytesN<16>,
)

Process a pending queued redemption.
Processing burns the escrowed USDM and pays collateral from the
beneficiary to the queued recipient. The pending records are deleted
before token movement so the ledger state no longer advertises an
executable pending redemption after this point in the invocation.

fn process_redemption(
    env: soroban_sdk::Env,
    admin: soroban_sdk::Address,
    redemption_id: soroban_sdk::BytesN<16>,
)

fn get_pending_redemption_id(
    env: soroban_sdk::Env,
    redeemer: soroban_sdk::Address,
) -> Option>

Atomic deposit via permit + price attestation (port of EVM deposit).
The caller authorizes the Soroban invocation, while the signed permit
binds the source, recipient, collateral, USDM token, amount, nonce, and
validity window that m1api approved off chain.
Verifies collateral price attestation if the collateral requires it.
Verifies USDM1 price attestation if token_id == 1.
Verifies and consumes the deposit permit (signed by trusted signer).
Converts amount via price indices, transfers collateral from source
to beneficiary through allowance, and mints USDM to recipient.
Fees, whitelist eligibility, and redemption limits are enforced before
signing; the contract enforces the signed quote and permit.

fn deposit(
    env: soroban_sdk::Env,
    source: soroban_sdk::Address,
    recipient: soroban_sdk::Address,
    collateral: soroban_sdk::Address,
    amount: i128,
    token_id: u32,
    collateral_price: PriceAttestation,
    usdm_price: PriceAttestation,
    permit: DepositPermitAttestation,
)
