* Initial commit * Initial commit based on LI.FI intent system * Use relative instead of fixed imports * Use interfaces for tests to more easily reuse tests externally * move codecov config into top level * Move contract implementation into top-level * fix github action * Refactor test for better external execution * expose filled outputs * consolidate finalise functions into two * fix tests * use library address in tests * fix coverage * Remove single solver validation code * Use custom error * use calldata for solvers * revert to using memory because of stack too deep error * revert to using memory instead of calldata * Standardise chainid maps for oracles (#3) * Standardize chainid maps for oracles Implements standardized chainid maps for oracles. This also lets oracles opt out of mapping in case they conform to a chainid standardization. This applies to Polymer for EVM chains. The advantage of non-mapped oracles is that they are ownerless making the system entirely permissionless and providing a base implementation that is entirely configless: **One deterministic deployment** * Fix overwrite implementation of the map in Polymer * Large refactoring pass to cleanup documentation, variable naming, and more. (#2) * Initial documentation pass of everything except oracles and input settlers and readme * typos * Complete the contracts and libraries * Update readme * grammar * Output chain instaed of destination chain * Apply suggestions from code review Co-authored-by: Gustavo Gonzalez <ggonzalezsomer@gmail.com> * Rename IOIFCallback to IOpenIntentCallback * Rename inputs callback and fillBatch * delete unused tests * review comments: Remove remote references * update test encoding --------- Co-authored-by: Gustavo Gonzalez <ggonzalezsomer@gmail.com> * Upgrade compact version to post audit fixes (#6) * Initial documentation pass of everything except oracles and input settlers and readme * typos * Complete the contracts and libraries * Update readme * grammar * Output chain instaed of destination chain * Apply suggestions from code review Co-authored-by: Gustavo Gonzalez <ggonzalezsomer@gmail.com> * Rename IOIFCallback to IOpenIntentCallback * Rename inputs callback and fillBatch * delete unused tests * Upgrade compact version to post audit fixes * Apply suggestions from code review Co-authored-by: jsanmigimeno <8038323+jsanmigimeno@users.noreply.github.com> --------- Co-authored-by: Gustavo Gonzalez <ggonzalezsomer@gmail.com> Co-authored-by: jsanmigimeno <8038323+jsanmigimeno@users.noreply.github.com> * Disallow intents from settler (#7) * Initial documentation pass of everything except oracles and input settlers and readme * typos * Complete the contracts and libraries * Update readme * grammar * Output chain instaed of destination chain * Apply suggestions from code review Co-authored-by: Gustavo Gonzalez <ggonzalezsomer@gmail.com> * Rename IOIFCallback to IOpenIntentCallback * Rename inputs callback and fillBatch * delete unused tests * Upgrade compact version to post audit fixes * Disallow intents from settler --------- Co-authored-by: Gustavo Gonzalez <ggonzalezsomer@gmail.com> * use memory-safe for assembly blocks (#33) * Move LibAddress to the protocol and use it inside the contracts (#9) * Refactor LibAddress: Move and enhance address identifier conversion library * remove ownbale, pausable that cursor added for no reason * add using for bytes32 and remove unnecesary md file * fmt * fix order of using * use assembly in toIdentifier * remove unnecesary import --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Alexander <git@lindgren.xyz> * Improve naming of message decoding function (#21) * Fix typos found in audit (#27) * Remove incorrect natspec comment amount destination of funds based on the set destination (#26) * 119 minutes is returned instead of 181 minutes if confirmations is 0 for _getProofPeriod (#20) * Fix stale finalise natsepc comment (#24) * Correct dublicate typecast in comments (#22) * Fix order purchase natspec comment (#23) * remote dublicate SignatureCheckerLib import (#25) * Optimise output hash (#32) * Only compute order id once.

LIFI's test.yml already runs forge build/test over the whole in-tree tree (incl. OIF's tests); evm-test.yml only added forge fmt --check + --gas-snapshot-check, which the LIFI team had deliberately removed (3cda515 "No fmt check", b1a7f6d "Remove snapshot check from ci"). Extend test.yml coverage excludes to OIF's vendored oracle externals (integrations/oracles/.*/external). Verified post-fork: full suite green — 382 tests, 0 failed, 0 skipped; default + Tron (solc 0.8.35) builds pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fork: restore OIF MIT notice + adopt OIF upstream dependency pins - Add LICENSE-MIT with upstream OIF's MIT license and copyright notice (the notice previously traveled with lib/OIF/LICENSE and was lost when the submodule was vendored in-tree); point README's OIF entry at it. - Align shared dependency pins with OIF main (39df288): forge-std 77041d2 -> 100b0d7 (v1.11.0), the-compact b9c3b54 -> ac25e50 (V1), in both the submodules and foundry.lock. - the-compact ac25e50 pins pragma =0.8.30, which the Tron profile's solc 0.8.35 cannot satisfy. Add a skip list to [profile.tron] for the-compact and its dependents, mirroring the --skip flags already documented in script/tron/deploy-oif.ts (the Tron deploy never uses the compact settler; its artifacts are unaffected). Verified: forge build (default + tron profiles) and full suite green (382 tests, 0 failed). Gas snapshots intentionally not regenerated: local nightly foundry produces materially different values than the committed baseline; regenerate deliberately on a pinned version.

Goal:
Add support for an off-chain auction. That is an auction taking place on an order server where off-chain solvers bid. This PR does not define how the auction works. This can be defined in the future by setting the first byte of the fulfillment context.
Be warned:
bytes1(TYPE) | bytes32(signer) | ...but the solver provides it asuint256(trueAmount) | bytes1(TYPE) | bytes32(signer) | ...
