Class OnchainSendGates

Namespace

NArk.ArkadeIntents.Onchain

Assembly

NArk.ArkadeIntents.dll

The checks run immediately before an onchain send is funded — never at quote time.

Remarks

This corridor's danger is not in either contract but in the relationship between them. Two deadlines on two chains govern one swap, and getting their order wrong is the single failure that can cost both legs at once, which is why it is checked here rather than left to the solver.

Fields

ClaimMarginSeconds

Time that must remain to claim on L1 after the funding has confirmed.

public const long ClaimMarginSeconds = 5400

Field Value

long

MaxMinConfirmations

The most confirmations this corridor will wait for before claiming.

public const int MaxMinConfirmations = 6

Field Value

int

Remarks

A ceiling, not a preference: a solver naming a large number turns the claim window into a wait the locktime may not outlast, and the quote is refusable now rather than stuck later.

MinHeadroomSeconds

Minimum time before the Arkade refund opens, mirroring the Lightning send leg.

public const long MinHeadroomSeconds = 5400

Field Value

long

OrderMarginSeconds

How far the Arkade refund must open after the L1 one.

public const long OrderMarginSeconds = 7200

Field Value

long

Remarks

Reorg margin. The solver takes the Arkade side using the preimage the client's L1 claim revealed, so the client's own Arkade refund must be the last door to open — otherwise there is a window in which the client can reclaim on Arkade while the solver can still reclaim on L1, and one leg pays for both.

SecondsPerBlock

Nominal seconds per block, for turning a confirmation count into a wait.

public const long SecondsPerBlock = 600

Field Value

long

Methods

AssertFundable(RfqQuote<OnchainSendQuoteProfile>, long)

Refuse a quote this corridor cannot safely fund.

public static void AssertFundable(RfqQuote<OnchainSendQuoteProfile> quote, long now)

Parameters

quote RfqQuote<OnchainSendQuoteProfile>

The solver's quote.

now long

The current time, unix seconds.

Exceptions

OnchainSendNotFundableException

Any check refused.

ClaimWindowIsOpen(long, long)

Whether there is still time to claim the L1 HTLC before its refund leaf opens.

public static bool ClaimWindowIsOpen(long htlcLocktime, long now)

Parameters

htlcLocktime long

When the counterparty's refund leaf matures, unix seconds.

now long

Unix seconds.

Returns

bool

true while claiming is still safe.

Remarks

Claiming near the locktime is a race that can be lost after showing our hand: a broadcast that does not confirm before the counterparty's refund does leaves it with its sats back and our preimage out of the mempool, which takes the Arkade side too. Both legs, for the sake of a few minutes. Declining costs only the covenant refund, which is still ours.
