Settlement currencies
You nominate the token and chain you want to be paid in. If the payer sends something else, the flow converts on the way. You receive what you configured, regardless of what arrived. More than one settlement can be configured on a flow. Each needs a matching destination on the same chain, so a flow that accepts USDC on two chains needs somewhere for each to land.Routing strategy
When several routes could satisfy a settlement, a strategy decides which one is used:
Preferred order is the one to reach for when you have a genuine preference between tokens or chains rather than a preference about cost or speed.
Source chains
A payer can pay from EVM, Solana, Sui, Bitcoin, or TRON. That is independent of what you settle in, so a payer holding an asset on one chain can pay a merchant settling on another without bridging anything themselves.Destinations
Funds settle to an address you provide. That can be a Fireblocks vault, a Dynamic embedded wallet, or any other address you control. Each destination is matched to a settlement by chain. For a withdrawal, the destination is the end user’s wallet and is supplied per flow, which is how a shared treasury pays out to many different users.Cross-chain orchestration
Cross-chain settlement orchestration is on by default. Turning it off keeps a flow on a single chain, which is worth doing when you have no intention of accepting cross-chain payments and would rather a mismatched source failed than be routed.Memos and reconciliation
Any flow can carry a memo, which is the mechanism for tying a payment back to something in your own system: an order ID, a user account, an invoice number. A memo persists through the whole lifecycle and appears in every webhook payload. Memos also satisfy chain-level requirements. Networks such as Cosmos need a memo or tag to route funds correctly, so the field does double duty. For reconciliation, pair the memo with the settlement transaction hash reported when settlement completes. See Webhooks and events.Next
