deposit-withdraw-flow.sh

#!/usr/bin/env bash
# End-to-end integration example: initialize -> deposit -> withdraw against
# the mergefi-maintenance-pool contract, chaining the same
# `node scripts/invoke.mjs` calls a real integrator would use.
#
# This is deliberately the deposit/withdraw flow rather than escrow's
# fund/release: release's `recipients` argument is a Vec<(Address, u32)>,
# which scripts/invoke.mjs's CLI argument parser can't encode yet (that's
# the separate, already-filed "no generated TypeScript bindings" /
# argument-encoding gap, tracked independently of this example). Every call
# below uses only address/u64/i128 arguments, which invoke.mjs already
# supports, so the whole flow is actually runnable as shown.
#
# Usage:
#   ADMIN_SECRET=S... \
#   ORACLE_SECRET=S... \
#   SPONSOR_SECRET=S... \
#   TOKEN=C... \
#   CONTRACT_ID=C... \
#     ./scripts/examples/deposit-withdraw-flow.sh
#
# CONTRACT_ID may be omitted to deploy a fresh mergefi-maintenance-pool
# instance as part of the flow (requires WASM_PATH to point at the built
# .wasm, see README's "Build, test, deploy" section).
#
# All variables below default to placeholders — replace them with funded
# testnet keys/addresses before running for real, or export the
# corresponding env vars.
