PropAMM SDK

Appearance

Changelog ​

All notable changes to the Python SDK (propamm) are documented here.

[1.3.0] - 2026-09-07 ​

Added ​

  • EL_ZORRO venue constant in common.pamms, plus its elzorro entry in PAMMS.

Removed ​

  • TokenOutBalanceDecreased from the bundled router ABI. The router stopped reverting with it when the bespoke Bebop adapter was removed, so it is no longer part of the compiled ABI and no longer decodes from a revert. (#67)

[1.2.0] - 2026-08-28 ​

Added ​

  • TEMPEST, TAURUSFI and METRIC venue constants in common.pamms, plus their tempest / taurusfi / metric entries in PAMMS.

Changed ​

  • BEBOP now points at 0xB09AaA5614916d7AEb59C295C52c92ca82aDdD76, the current Bebop deployment. Code that hardcoded the previous Bebop address must be updated.

Removed ​

  • _LEGACY_BEBOP_LOWER and the legacy-Bebop handling in to_state_override. The superseded Bebop deployments are no longer whitelisted on the router, so they can be neither quoted nor dispatched and need no price neutralization; bebop_default now zeroes only the current BEBOP slot when a snapshot omits it.

[1.1.3] - 2026-07-01 ​

Added ​

  • The swap and swap_and_wait functions now attach a hardcoded per-function gas limit and skip gas estimation, which can under-shoot when execution takes a heavier branch than it simulated. Override the gas limit per call with the new SwapOptions.gas_limit.

[1.1.2] - 2026-06-25 ​

Fixed ​

  • State-override quotes now pin the simulated block.timestamp to the beacon slot's canonical block time (genesis + slot*12) instead of the frame's emit time, falling back to the emit time when no slot is present. Venues validate block.timestamp against the state they pushed, which is keyed to the slot. (#63)

[1.1.1] - 2026-06-24 ​

Added ​

  • Price levels: subscribe to maker price-level updates and apply them to quotes via PriceLevelsWsSource (WebSocket) or PriceLevelsRpcSource (RPC), plus the PriceLevels container and related utilities. (#53)
  • Optional RPC URL argument on the client constructor. (#53)

[1.0.0] - 2026-06-19 ​

Added ​

  • Initial release. Core surface for interacting with the PropAMMRouter:
    • Router actions: quote, swap, wait_for_swap, approve, allowance, and view helpers.
    • State overrides: apply fresh pAMM state to quotes via OverridesWsSource (WebSocket) or OverridesRpcSource (RPC), plus utilities.
    • Shared helpers and types.
