+# CW1 Multisig
+
+This may be the simplest implementation of CW1, a "1 of N" multisig.
+It contains a set of admins that are defined upon creation.
+Any of those admins may `Execute` any message via the contract,
+per the CW1 spec.
+
+To make this slighly less minimalistic, you can allow the admin set
+to be mutable or immutable. If it is mutable, then any admin may
+(a) change the admin set and (b) freeze it (making it immutable).
+
+While largely an example contract for CW1, this has various real-world use-cases,
+such as a common account that is shared among multiple trusted devices,
+or trading an entire account (used as 1 of 1 mutable). Most of the time,
+this can be used as a framework to build your own, more advanced cw1 implementations.
+
+## Allowing Custom Messages
+
+By default, this doesn't support `CustomMsg` in order to be fully generic
+among blockchains. However, all types are Generic over `T`, and this is only
+fixed in `handle`. You can import this contract and just redefine your `handle`
+function, setting a different parameter to `HandleMsg`, and you can produce
+a chain-specific message.
+
+## Running this contract
+
+You will need Rust 1.41+ with `wasm32-unknown-unknown` target installed.
+
+You can run unit tests on this via: 
+
+`cargo test`
+
+Once you are happy with the content, you can compile it to wasm via:
+
+```
+RUSTFLAGS='-C link-arg=-s' cargo wasm
+cp ../../target/wasm32-unknown-unknown/release/cw20_escrow.wasm .
+ls -l cw20_escrow.wasm
+sha256sum cw20_escrow.wasm
+```
+
+Or for a production-ready (compressed) build, run the following from the
+repository root (not currently working with this monorepo...)
+
+```
+docker run --rm -v "$(pwd)":/code \
+  --mount type=volume,source="cosmwasm_plus_cache",target=/code/target \
+  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
+  cosmwasm/rust-optimizer:0.8.0 ./contracts/cw20-base
+mv contract.wasm cw20_escrow.wasm
+```
