# BIP-39 seed phrase for the deployer EOA. Used by:
#   1. The multi-chain deploy wrapper (scripts/deploy-v3-multichain.sh) — index 0.
#      Required even in DRY_RUN mode (forge simulation needs --mnemonics,
#      and the wrapper derives the deployer address for per-chain balance
#      checks).
#   2. The V3 integration tests (test/integration/V3DutchOrderIntegration.t.sol)
#      — indexes 1 (swapper) / 2 (filler) / 3 (cosigner). When unset, the
#      tests fall back to deterministic keccak-derived keys.
DEPLOYER_MNEMONIC=

# Deploy script (script/DeployDutchV3.s.sol). Set when invoking the script
# directly; the multi-chain wrapper sets these per chain from
# playbook/chains/salts.json and ignores the values here.

# Pin the fork to a specific block. Required on chains with sub-second block
# times (Tempo) where public RPCs prune state faster than forge resolves
# the fork. Get a recent block via:

# (Swapper / filler / cosigner keys are derived from DEPLOYER_MNEMONIC at
# HD indexes 1 / 2 / 3; see the DEPLOYER_MNEMONIC comment above.)
# Optional trade-amount overrides for tier-2 / tier-3.
#
# Tier-2 (off-chain quote) and tier-3 (end-to-end fill) deploy fresh
# MockERC20 contracts on the fork as the trade tokens — Tempo's TIP-20
# stablecoins (0x20c0...) revert with OpcodeNotFound under Foundry's local
# EVM. Mocks let us still exercise the real reactor, real Permit2, real
# cosignature path; only the trade tokens are substituted.
#
# Defaults: 1_000_000 in -> 999_000 out (6 decimals; 0.1% spread).
