Yield Sources - Ground

Yield sources are the underlying strategies a portfolio wallet can allocate into. A wallet strategy is a weighted allocation across one or more yield sources. Each source has a stable public id, display metadata, chain support, risk metadata, current rate information, and optional market context such as TVL, vault-level utilization, protocol addresses, vault links, and top underlying allocations when provider data is available.

Example APYs and market context values above are illustrative. Always use GET /v2/wallets/yield-sources for the current live catalog and rates.

The catalog is environment-specific. Sandbox only exposes the subset that is currently wired for sandbox execution. Do not hard-code yield source IDs by environment; always fetch the live catalog before creating or updating a strategy.

Yield source ID	Liquidity	Description
`syrup-usdc`	Typically within 24h (`PT24H`)	Overcollateralized USDC lending via Maple Finance’s Syrup.
`morpho-gauntlet-usdc`	Instant (`PT0H`)	ERC-4626 lending vault exposure via Morpho’s Gauntlet USDC Prime vault.
`morpho-steakhouse-usdc`	Instant (`PT0H`)	ERC-4626 lending vault exposure via Morpho’s Steakhouse USDC Prime vault.
`kamino-allez-usdc`	Instant (`PT0H`)	Solana USDC yield via a Kamino kvault curated by Allez.

`kamino-superstate-usdc`	Instant (`PT0H`)	Solana USDC yield via a Kamino klend reserve collateralized by Superstate.

Use id as the yieldSourceId when creating a wallet or updating a strategy. Catalog rows may also include optional market context for richer source displays:

Field	Description
`tvlUsd`	Current source TVL in USD when provider data is available.
`utilizationPct`	Vault-level deployed-asset utilization percentage when provider data is available.
`addresses[]`	Protocol addresses relevant to the source.
`links[]`	Provider UI links for the source.
`allocations[]`	Current underlying allocation rows. Percentages describe source asset mix, not utilization.

Yield source details

Syrup USDC


Yield source ID	`syrup-usdc`
Type	Overcollateralized lending
Chain	Ethereum
Liquidity	Typically within 24 hours

Syrup USDC is an overcollateralized lending product from Maple Finance. Deposits and withdrawals are handled through an ERC-4626 vault, but withdrawals can still be queue-based depending on protocol liquidity.

Morpho Gauntlet USDC Prime


Yield source ID	`morpho-gauntlet-usdc`
Type	Overcollateralized lending
Chain	Ethereum
Liquidity	Instant

This source allocates into the Morpho Gauntlet USDC Prime ERC-4626 vault. Ground values the position from onchain convertToAssets() reads and computes the displayed APY from trailing NAV/share history.

Morpho Steakhouse USDC Prime


Yield source ID	`morpho-steakhouse-usdc`
Type	Overcollateralized lending
Chain	Ethereum
Liquidity	Instant

This source allocates into the Morpho Steakhouse USDC Prime ERC-4626 vault. It shares the same portfolio-wallet mechanics as Gauntlet but tracks a separate underlying Morpho vault.

Kamino Allez USDC


Yield source ID	`kamino-allez-usdc`
Type	Curated kvault (Solana)
Chain	Solana
Liquidity	Instant

Kamino Allez USDC is a Solana-native USDC yield vault curated by Allez on Kamino. Allocations are held as kvault shares; Ground values the position from the onchain share price and unwinds via Kamino’s kvault withdraw path.

Kamino Gauntlet USDC Frontier


Yield source ID	`kamino-gauntlet-frontier-usdc`
Type	Curated kvault (Solana)
Chain	Solana
Liquidity	Instant

A Kamino kvault curated by Gauntlet’s Frontier mandate. USDC deposits are routed across Kamino reserves selected by the curator; yield and NAV are derived from onchain share pricing.

Kamino RockawayX RWA USDC


Yield source ID	`kamino-rockawayx-rwa-usdc`
Type	Curated kvault (Solana, RWA-tilted)
Chain	Solana
Liquidity	Instant

A Kamino kvault curated by RockawayX with a real-world-asset tilt. Same portfolio-wallet mechanics as other Kamino kvaults; the strategy mix differs.

Kamino Steakhouse USDC


Yield source ID	`kamino-steakhouse-usdc`
Type	Curated kvault (Solana)
Chain	Solana
Liquidity	Instant

A Kamino kvault curated by Steakhouse Financial. Accepts USDC deposits, issues share tokens, and yields through Kamino’s lending markets as directed by the curator.

Kamino Superstate USDC


Yield source ID	`kamino-superstate-usdc`
Type	Kamino klend reserve (Superstate-collateralized)
Chain	Solana
Liquidity	Instant

Superstate USDC is a Kamino klend reserve directly (rather than a curated kvault). Supplies liquidity against Superstate-backed collateral; unwinds call the reserve’s redeem_reserve_collateral path. Position value is derived from the reserve’s current collateral exchange rate.

Rate semantics

apyBps is an annualized yield figure in basis points.
syrup-usdc uses Maple’s Syrup rate feed.
Morpho ERC-4626 vaults exposed by the live catalog use trailing APR derived from ERC-4626 NAV/share history.
Kamino kvaults and klend reserves use trailing APR derived from Kamino’s onchain share price / collateral exchange rate history.
All rates are variable and may change over time.

NAV freshness

syrup-usdc is valued from an onchain ERC-4626 convertToAssets() read.
Morpho ERC-4626 vaults exposed by the live catalog are also valued from onchain ERC-4626 convertToAssets() reads.
Kamino kvaults are valued from the onchain share price (shareValueInAssets) read via Kamino’s kvault SDK.
Kamino klend reserves (e.g. Superstate) are valued from the reserve’s onchain collateralExchangeRate.

`protocol`

protocol is a lowercase slug identifying the issuer or curating protocol for the yield source. Multiple yield sources can share the same protocol (e.g. all Morpho vaults have "protocol": "morpho").

Value	Protocol
`morpho`	Morpho Labs
`maple`	Maple Finance
`kamino`	Kamino Finance
`resolv`	Resolv
`superstate`	Superstate

Use protocol to apply protocol-level concentration limits in POST /v2/wallets/strategy/optimize.

`estimatedWithdrawalTime`

estimatedWithdrawalTime is an ISO 8601 duration representing the worst-case yield-source unwind time (SLA upper bound), also referred to as maxProcessingTime in the optimization API.

Duration	Meaning
`PT0H`	Immediate
`PT24H`	Up to roughly 24 hours

Use POST /v2/wallets/:id/withdrawal-preview when you need wallet-specific withdrawal timing rather than source-level estimates.

`expectedProcessingTime`

expectedProcessingTime is an ISO 8601 duration representing the typical withdrawal completion time for a source — distinct from estimatedWithdrawalTime, which is the SLA upper bound. For sources with predictable queue-based settlement, the expected time may be shorter than the maximum.

Duration	Meaning
`PT0H`	Typically completes immediately
`PT12H`	Typically completes within ~12 hours
`PT24H`	Typically completes within ~24 hours
