Release v12.9.0 · ProjectOpenSea/opensea-sdk

What's Changed

Arc support (Chain.Arc, chain id 5042): offers use the 6-decimal USDC native mirror (0x3600…0000), listings use native USDC, approvals use the OS Ledger conduit.
Stable Chain support (Chain.StableChain, chain id 988): offers use the 6-decimal USDT0 native mirror (0x779d…3736), listings use native gUSDT0, approvals use the OS Ledger conduit.
On both chains, a native (0x0) offer currency advertised by the API is normalized to the mirror before approvals, amount conversion and signing; explicit mirror addresses pass through unchanged. wrapEth/unwrapWeth throw on these chains, since there is no wrapped native token — offers spend the native balance directly.
Sync OpenAPI spec: arc chain identifier; agent relationships gain ConfirmAgentRelationshipRequestBody and optional counterparty_account_id addressing. revokeAgentRelationship serializes whichever counterparty identifier is provided (counterpartyAccountId or counterpartyAddress).
Depends on @opensea/api-types@0.12.0.

Stop forwarding chain on getEventsByCollection and getEventsByNFT; only the account events endpoint documents that filter — thanks @Osraka (opensea-sdk#2011, fixes opensea-sdk#2010)
