Smart contracts for Rarible Protocol

Consists of:

See more information about Rarible Protocol at docs.rarible.org.

Also, you can find Rarible Smart Contracts deployed instances across Mainnet, Testnet and Development at Contract Addresses page.

Compile, Test, Deploy

yarn
yarn bootstrap

if error, check node version for yarn expected node version ">=14.18.2", for check and set necessary version use, for example

node -v
nvm use 18.13.0

then use truffle to compile, test: cd into directory and then

truffle test --compile-all

Protocol overview

Rarible protocol is a combination of smart-contracts for exchanging tokens, tokens themselves, APIs for order creation, discovery, standards used in smart contracts.

The Protocol is primarily targeted to NFTs, but it's not limited to NFTs only. Any asset on EVM blockchain can be traded on Rarible.

Smart contracts are constructed in the way to be upgradeable, orders have versioning information, so new fields can be added if needed in the future.

Trade process overview

Users should do these steps to successfully trade on Rarible:

  • Approve transfers for their assets to Exchange contracts (e.g.: call approveForAll for ERC-721, approve for ERC-20) — amount of money needed for trade is price + fee on top of that. Learn more at exchange contracts README.
  • Sign trading order via preferred wallet (order is like a statement "I would like to sell my precious crypto kitty for 10 ETH").
  • Save this order and signature to the database using Rarible protocol API (in the future, storing orders on-chain will be supported too).

If the user wants to cancel the order, he must call cancel function of the Exchange smart contract.

Users who want to purchase something on Rarible should do the following:

  • Find an asset they like with an open order.
  • Approve transfers the same way (if not buying using Ether).
  • Form order in the other direction (statement like "I would like to buy precious crypto kitty for 10 ETH").
  • Call Exchange.matchOrders with two orders and first order signature.
