Evalanche v1.8.7

Evalanche v1.8.7

This release hardens live execution and canonical-chain DeFi routing, with the fixes validated against funded wallets and a full green test/build pass.

Highlights

• Polymarket live execution fixes:

  • pm_buy now uses the SDK-compatible buy-order nonce path again, fixing live invalid nonce failures.
  • pm_buy surfaces venue rejections honestly, including geoblocking and min-order-size errors.
  • pm_balances now reports allowance consistently from the true source of truth, including allowanceSource and matching rawAllowance.
  • live funded pm_buy was verified end to end with venue reconciliation.

• Canonical-chain DeFi fixes:

  • yoUSD vault reads and quote paths now route cleanly to Base from MCP.
  • sAVAX quote paths now route cleanly to Avalanche from MCP.
  • vault metadata/quote reads were hardened for flaky public RPC behavior by disabling provider batching and making metadata reads deterministic.
  • savax_unstake_quote now degrades to delayed-only when instant pool balance probing reverts instead of failing the whole quote.

• Hyperliquid live execution hardening:

  • market order price/size normalization was fixed for low-priced assets.
  • live tiny trade and close-position verification succeeded after the fix.

• Polymarket discovery/runtime fixes:

  • stale/malformed market search handling was tightened.
  • venue-truth reconciliation remains the authority for execution reporting.
