Supported Chains & Protocols

Copy page

The Binance Web3 DeFi API currently supports BNB Smart Chain (BSC). More chains and protocols will be supported in upcoming releases.

Supported Chains

#	Chain	Short Name	Chain ID	Native Asset
1	BNB Smart Chain	BSC	56	BNB

Supported Protocols

Protocol data queries (protocol / investment discovery) and transaction building are available for the following protocols on BSC. Each protocol may expose one or more investment types (Earn, LiquidityPool).

Position queries (POST /api/v1/defi/data/position/list) cover a wider set of protocols — see Position Coverage below.

Protocol	defiProtocolId	Investment Types	Transaction Build
Venus	venus	Earn	deposit / redeem / claim
Venus Flux	venusflux	Earn	deposit / redeem
Lista DAO	helio	Earn	deposit / redeem
Aave V3	aave3	Earn	deposit / redeem
Aster	astherus	Earn	deposit / redeem / claim
Solv	solv	Earn	deposit / redeem / claim
Uniswap V3	uniswap3	LiquidityPool	lp-add / lp-remove / claim
Uniswap V4	uniswap4	LiquidityPool	lp-add / lp-remove / claim
PancakeSwap V3	pancakeswap3	LiquidityPool	lp-add / lp-remove / claim
PancakeSwap Infinity	pancakeswap4	LiquidityPool	lp-add / lp-remove / claim

The defiProtocolId values above are representative; always use POST /api/v1/defi/data/protocol/list to fetch the authoritative, up-to-date list (server-side configured and subject to change).

Position Coverage

Position queries (POST /api/v1/defi/data/position/list) cover the protocols below on BSC — a wider set than the transaction/investment list above.

Protocol	defiProtocolId
Venus	venus
Venus Flux	venusflux
Lista DAO	helio
Aave V3	aave3
Aster	astherus
Solv	solv
Lorenzo Protocol	lorenzoprotocol
NestCredit	nestcredit
Unitas	unitas
Uniswap V2	uniswap2
Uniswap V3	uniswap3
Uniswap V4	uniswap4
PancakeSwap V2	pancakeswap
PancakeSwap V3	pancakeswap3
PancakeSwap Infinity	pancakeswap4

Note the difference when integrating:

• A position returned for a protocol inside the transaction/investment list above carries valid investmentIds; you can follow up with investment queries and transaction building.
• A position returned for a protocol only in this position list is display-only — its investmentIds may be empty, and transaction building is not available for it. Do not assume every returned position can act as the entry point of a transaction.

The only way to tell whether an investmentIds value is valid: look it up via POST /api/v1/defi/data/investment/list (or /investment/detail). Even if the position response carries investmentIds, they are invalid when the investment queries return no match — they cannot be used for transaction building, and build calls with them will fail.

Current Limitations

• Redeem waiting period: some protocols (e.g. Lista helio, Aster astherus) impose a waiting period before redeemed funds become claimable. The build response carries it as data.redeemDelayDays (a [min, max] day pair; [] = instant) — read it from every /transaction/redeem call before proceeding with signing. See Integration Flow.
• BSC only; more chains and protocols will be added in upcoming releases.
