Each adaptor fetches stake pool data and SOL pricing, calculates APY and pool metrics, and exports protocol metadata. ChangesPhase Solana adaptors
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds two read-only Phase yield feeds, but stale stake-pool snapshots could publish incorrect TVL/APY and an upstream request that stalls indefinitely could prevent refreshes. These are localized correctness and availability risks, so the change is mergeable with explicit owner awareness and follow-up. Sequence Diagram(s)sequenceDiagram

Axios 1.7.2 default timeout 0 request config documentation
💡 Result:
In Axios, including version 1.7.2, the default value for the timeout request configuration property is 0 [1][2][3]. A timeout value of 0 indicates that there is no timeout applied to the request [1][4][5]. When set to 0, Axios will not automatically abort the request, allowing it to potentially hang indefinitely if the server does not respond [3]. It is recommended to explicitly set a timeout value (in milliseconds) for production environments to prevent stalled requests from hanging indefinitely [3]. You can define this value globally, in an Axios instance, or on a per-request basis [6][7]. Example usage: // Global default axios.defaults.timeout = 5000; // Instance default const instance = axios.create({ timeout: 2500 }); // Per-request override instance.get('/endpoint', { timeout: 10000 });

Add deadlines to the Solana RPC and price requests.
getStakePoolInfo(STAKE_POOL) performs two axios.post RPC requests, and apy() performs one axios.get request. Axios defaults to no timeout. A stalled upstream can keep apy() pending and prevent metrics from refreshing. Add bounded, abortable timeouts to all three requests.

Solana SPL stake pool state.rs last_update_epoch total_lamports inaccurate current epoch official source
💡 Result:
The total_lamports field in the Solana SPL Stake Pool state is not guaranteed to be accurate if the last_update_epoch does not match the current epoch [1][2][3]. As specified in the official SPL Stake Pool source code (state.rs), this field represents the total stake under management but is only updated when the stake pool balance is synchronized [1][2]. Because stake rewards and balance changes occur at the epoch boundary, the stake pool program must be explicitly updated to reflect the new state [4][5]. Key points regarding this behavior: 1. Inaccurate State: If the last_update_epoch is older than the current epoch, the total_lamports and active_stake_lamports (within ValidatorStakeInfo) may not reflect current network conditions [1][2]. 2. Permissionless Updates: The UpdateStakePoolBalance instruction is permissionless, meaning any user can (and must) trigger it to synchronize the pool's data for the current epoch [4][6]. 3. Interaction Failure: If a stake pool has not been updated for the current epoch, certain instructions (such as deposits or withdrawals) may fail [4]. 4. Recommended Practice: Developers should ensure that an update instruction has been processed for the current epoch before relying on total_lamports for critical calculations like rewards or token price estimations [4][7]. The SPL Stake Pool CLI and SDKs typically include functions to perform this update automatically as a convenience before executing other operations [4].

Reject stale stake-pool snapshots before reporting APY or TVL.
When lastUpdateEpoch lags the current epoch, totalLamports can be stale. The adapter publishes this value through tvlSol, and calcSolanaLstApy annualizes the rate change as one epoch without using the elapsed epoch count. Reject stale snapshots or annualize growth over the elapsed epochs.

The phase-delegation adapter exports pools: Test Suites: 1 passed, 1 total |

Thanks, fixed the two price-guard findings in both adapters. On the stale snapshot point: both of these pools update every epoch, Related, and possibly worth a separate look: The lifetime average is dragged down by Solana's earlier, slower epochs, so annualising a single epoch's growth by 158.7 understates APY by roughly 40% for every adapter on this path. For pdSOL it is the difference between the 3.79% this PR currently reports and ~5.5%. Deriving I did not want to change shared utils in a listing PR, so flagging rather than patching. Happy to open a separate PR for it if useful. |

One thing worth flagging: the CI run only exercised It is almost certainly fine, since the two files are structurally identical and only differ in addresses, but I would rather you knew than have it merge untested. Verified locally against the same For reference, the same method reproduces Note that YIELD's pool runs on the Sanctum multi-validator stake pool program ( |

Happy to get this out of your queue. The adapters are ready as they stand. Both price-guard findings are fixed, CI is green, and the diff touches only the two new adapter files. The Not a blocker from my side: the CI log only ran |

Note that YIELD's pool runs on the Sanctum multi-validator stake pool program (
