+# Terra Wormhole Contract Deployment
+
+This readme describes the steps for building, verifying, and deploying Terra smart contracts for Wormhole.
+
+**WARNING**: *This process is only Linux host compatible at this time.*
+
+## Verify Tilt
+
+Before building Terra contracts, ensure that the specific commit you will be
+building from passes in tilt. This that ensures basic functionality of the
+Terra smart contracts that you are about to build and deploy.
+
+## Build Contracts
+
+The following command can be used to build Terra contracts via Docker.
+
+Build Target Options: [`mainnet`|`testnet`|`devnet`|
+
+These network names correspond to the naming convention used by wormhole
+elsewhere. This means that `mainnet` corresponds to Terra `mainnet`,
+`testnet` corresponds to Terra `testnet`, and `devnet` is `localterra`.
+
+```console
+wormhole/terra $ make artifacts
+```
+
+Upon completion, the compiled bytecode for the Terra contracts will be placed
+into the `artifacts` directory.
+
+## Verify Checksums 
+
+Now that you have built the Terra contracts, you should ask a peer to build
+using the same process and compare the equivalent checksums.txt files to make
+sure the contract bytecode(s) are deterministic.
+
+```console
+wormhole/terra $ cat artifacts/checksums.txt
+```
+
+Once you have verified the Terra contracts are deterministic with a peer, you can now move to the deploy step.
+
+## Run tests
+
+**Disclaimer: Currently the only test that exists is for the token bridge's transfer.**
+
+You can run the integration test suite on the artifacts you built.
+
+```console
+wormhole/terra $ make test
+```
+
+This command deploys your artifacts and performs various interactions with your
+contracts in a LocalTerra node. Any new functionality (including expected errors)
+to the contracts should be added to this test suite.
+
+## Deploy Contracts
+
+Now that you have built and verified checksums, you can now deploy one or more relevant contracts to the Terra blockchain.
+
+Deploy Target Options: [`mainnet`|`testnet`|`devnet`]
+
+You will need to define a `payer-DEPLOY_TARGET.json` for the relevant deploy
+target (eg. `payer-testnet.json`).  This will contain the relevant wallet
+private key that you will be using to deploy the contracts.
+
+```console
+wormhole/terra $ make deploy/bridge
+wormhole/terra $ make deploy/token_bridge
+wormhole/terra $ make deploy/nft_bridge
+```
+
+For each deployed contract, you will get a code id for that relevant
+contract for the deployment, make note of these so you can use them in
+the next step for on-chain verification.
+
+## Verify On-Chain
+
+Now that you have deployed one or more contracts on-chain, you can verify the
+onchain bytecode and make sure it matches the same checksums you identified
+above.
+
+For each contract you wish to verify on-chain, you will need the following elements:
+
+- Path to the contracts bytecode (eg. `artifacts-testnet/token_bridge.wasm`)
+- Terra code id for the relevant contract (eg. `59614`)
+- A network to verify on (`mainnet`, `testnet`, or `devnet`)
+
+Below is how to verify all three contracts:
+
+```console
+wormhole/terra $ ./verify artifacts/wormhole.wasm NEW_BRIDGE_CODE_ID
+wormhole/terra $ ./verify artifacts/token_bridge.wasm NEW_TOKEN_BRIDGE_CODE_ID
+wormhole/terra $ ./verify artifacts/nft_bridge.wasm NEW_NFT_BRIDGE_CODE_ID
+```
+Example: `./verify artifacts/token_bridge.wasm 59614`
+
+For each contract, you should expect a `Successfully verified` output message.
+If all contracts can be successfully verified, you can engage in Wormhole
+protocol governance to obtain an authorized VAA for the contract upgrade(s).
+
+A verification failure should never happen, and is a sign of some error in the
+deployment process.  Do not proceed with governance until you can verify the
+on-chain bytecode with the locally compiled bytecode.
+
+
+## Governance
+
+### Mainnet
+
+Upgrades on mainnet have to go through governance. Once the code is deployed in
+the previous step, an unsigned governance VAA can be generated
+
+```sh
+./generate_governance -m token_bridge -c 59614 > token-bridge-upgrade-59614.prototxt
+```
+
+This will write to the `token-bridge-upgrade-59614.prototxt` file, which can
+now be shared with the guardians to vote on.
+
+Once the guardians have reached quorum, the VAA may be submitted from any
+funded wallet: TODO - make this easier and more unified
+
+``` sh
+node main.js terra execute_governance_vaa <signed VAA (hex)> --rpc "https://lcd.terra.dev" --chain_id "columbus-5" --mnemonic "..." --token_bridge "terra10nmmwe8r3g99a9newtqa7a75xfgs2e8z87r2sf"
+```
+
+### Testnet
+
+For the contracts on testnet, the deployer wallet retains the upgrade
+authority, so these don't have to go through governance.
+
+For example, to migrate the token bridge to 59614, run in `tools/`:
+
+``` sh
+node migrate_testnet.js --code_id 59614 --contract terra1pseddrv0yfsn76u4zxrjmtf45kdlmalswdv39a --mnemonic "..."
+```

+# Cw721 Basic
+
+This is a basic implementation of a cw721 NFT contract. It implements
+the [CW721 spec](../../packages/cw721/README.md) and is designed to
+be deployed as is, or imported into other contracts to easily build
+cw721-compatible NFTs with custom logic.
+
+Implements:
+
+- [x] CW721 Base
+- [x] Metadata extension
+- [ ] Enumerable extension (AllTokens done, but not Tokens - requires [#81](https://github.com/CosmWasm/cw-plus/issues/81))
+
+## Implementation
+
+The `ExecuteMsg` and `QueryMsg` implementations follow the [CW721 spec](../../packages/cw721/README.md) and are described there.
+Beyond that, we make a few additions:
+
+* `InstantiateMsg` takes name and symbol (for metadata), as well as a **Minter** address. This is a special address that has full 
+power to mint new NFTs (but not modify existing ones)
+* `ExecuteMsg::Mint{token_id, owner, token_uri}` - creates a new token with given owner and (optional) metadata. It can only be called by
+the Minter set in `instantiate`.
+* `QueryMsg::Minter{}` - returns the minter address for this contract.
+
+It requires all tokens to have defined metadata in the standard format (with no extensions). For generic NFTs this may
+often be enough.
+
+The *Minter* can either be an external actor (eg. web server, using PubKey) or another contract. If you just want to customize
+the minting behavior but not other functionality, you could extend this contract (importing code and wiring it together)
+or just create a custom contract as the owner and use that contract to Mint.
+
+If provided, it is expected that the _token_uri_ points to a JSON file following the [ERC721 Metadata JSON Schema](https://eips.ethereum.org/EIPS/eip-721).
+
+## Running this contract
+
+You will need Rust 1.44.1+ 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/cw721_base.wasm .
+ls -l cw721_base.wasm
+sha256sum cw721_base.wasm
+```
+
+Or for a production-ready (optimized) build, run a build command in the
+the repository root: https://github.com/CosmWasm/cw-plus#compiling.
+
+## Importing this contract
+
+You can also import much of the logic of this contract to build another
+CW721-compliant contract, such as tradable names, crypto kitties,
+or tokenized real estate.
+
+Basically, you just need to write your handle function and import 
+`cw721_base::contract::handle_transfer`, etc and dispatch to them.
+This allows you to use custom `ExecuteMsg` and `QueryMsg` with your additional
+calls, but then use the underlying implementation for the standard cw721
+messages you want to support. The same with `QueryMsg`. You will most
+likely want to write a custom, domain-specific `instantiate`.
+
+**TODO: add example when written**
+
+For now, you can look at [`cw721-staking`](../cw721-staking/README.md)
+for an example of how to "inherit" cw721 functionality and combine it with custom logic.
+The process is similar for cw721.

+ * 
+ * Create a client:

+ * 
+ * Get the mnemonic:
+ *   await useOptions(pebblenetOptions).recoverMnemonic(password);

+ * 
+ * Upload contract:

+// NOTE: [External and internal token id conversion]
+// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+//
+// The CW721 NFT standard allows token ids to be arbitrarily long (utf8)
+// strings, while the token_ids in VAA payloads are always 32 bytes (and not
+// necessarily valid utf8).
+//
+// We call a token id that's in string format an "internal id", and a token id
+// that's in 32 byte format an "external id". Note that whether a token id is in
+// internal format or external format doesn't imply which chain the token id
+// originates from. We can have a terra (native) token id in both internal and
+// external formats, and likewise we can have an ethereum token in in both
+// internal and external formats.
+//
+// To support seamless transfers through the bridge, we need a way to have a
+// 1-to-1 mapping from internal ids to external ids.
+// When a foreign (such as ethereum or solana) token id first comes through, we
+// simply render it into a string by formatting it as a decimal number. Then,
+// when we want to transfer such a token back through the bridge, we simply
+// parse the string back into a u256 (32 byte) number.
+//
+// When a native token id first leaves through the bridge, we turn its id into a
+// 32 byte hash (keccak256). This hash is the external id. We store a mapping
+//
+//    (chain_id, nft_address, keccak256(internal_id)) => internal_id
+//
+// so that we can turn it back into an internal id when it comes back through
+// the bridge. When the token is sent back, we could choose to delete the hash
+// from the store, but we do not. This way, external token verifiers will be
+// able to verify NFT origins even for NFTs that have been transferred back.
+//
+// If two token ids within the same contract have the same keccak256 hash, then
+// it's possible to lose tokens, but this is very unlikely.
