Update listing

Builds a transaction repricing an existing listing to newPrice, signed by seller.

The listing must exist and belong to seller. Nothing else about it changes — currency, timing, edition limit and whitelist configuration are all preserved. To change those, cancel the listing and create a new one.

TypeScript Definitions

Reprices an existing listing. Nothing else changes — currency, timing, edition limit and whitelist configuration are preserved.

Wallet that created the listing (base58). Signs the transaction.

asset*string

Mint address of the listed artwork (base58).

newPrice*integer

Replacement price in the listing currency's base units.

Range1 <= value

targetPriorityFeeLamports?integer

Total priority fee to target for this transaction, in lamports. The builder derives the compute-unit price from it and the transaction's compute budget. Omit to let mallow pick a fee from current network conditions.

Formatuint64

blockhash?string

Recent blockhash to stamp onto the transaction, base58. Omit to let mallow supply one — mallow's is cached for up to 10 seconds, so two identical requests inside that window compile the same transaction, with the same signature once signed. Supply your own to control the expiry window, or when otherwise-identical requests must produce distinct transactions. Rejected with a 400 if it is not valid base58; a blockhash the cluster has already aged out builds fine and fails at send time.
