The Token Bridge is an interoperability protocol which allows users to move their own RSK or Ethereum ERC20 Tokens between networks in a quick and cost-efficient manner. The UI is available at:
Side Token is an ERC777 representation of a ERC20 compatible tokens which is on another network(could be on Ethereum or RSK network). The Side Token displays the exact same properties as the standard ERC20 token and allows it to be used in all the same places as ERC20.
Side Tokens are minted to prove cross chain bridges can work in a safe and secure manner with 2 standalone blockchains. We believe this kind of interoperability technology offers a lot of possibilities for smart contract owners, as they may prefer to do certain operations in one chain, and others in another one. By connecting blockchains with these bridges you allow for a variety of new use cases that never existed before.
No! It’s important to note that there will be no increase in the original tokens. The existing amount of circulating original tokens will stay the same and simply be distributed across 2 networks (RSK Network & Ethereum network) instead of 1.
The original token lives on the network that it was deployed for example Ethereum, while the Side Token is a representation of the original token on the other network, for example RSK.
The symbol of the Side Token is the original token symbol with an r
prefix if it is created in RSK or an e
prefix if it is created in Ethereum. For example, if we cross the RIF
token from RSK to Ethereum, the Side Token symbol would be eRIF
.
The number of decimal places will be 18. These are the ‘addresses’ of the deployed contracts in the different networks.
The Token Bridge will be a public DApp where users will be able to access by using Nifty Wallet or Metamask. You will be able to send your original tokens and receive an equivalent amount of Side Tokens on the other network. By toggling the network on Nifty or Metamask, you’re also able to transfer the other way around, by sending Side Tokens and receive original tokens.
Upon receiving your Side Tokens, you no longer own your original tokens. The moment you use the bridge to send them to the other network (RSK or Ethereum), they are locked up and stored in the contract address. Thus you effectively have no original tokens on the original network and now have Side Tokens on the other network.
There is no limit on the total. Hypothetically, the entire circulating supply can be bridged, though this is unlikely happen as there will be strong use cases to use the tokens on either network.
However, there are daily quotas:
During the trial period, only whitelisted tokens can cross the bridge. The federation is responsible for adding and removing tokens from the whitelist. When the trial period is over, and we move to a fully decentralized bridge, the whitelist will be removed.
The federation is paying and sponsoring the fees for the multiple transactions during the trial period. This will change after the trial period is complete, and the Token Bridge changes from a federated schema to a fully decentralized one. Users will need to pay a small amount of gas fee when using Metamask to submit transactions.
The Token Bridge functionality is quite unique, yet simple to understand. The ratio of tokens during network transfer always remains 1:1 and behaves in the following manner:
When original tokens are moved to the other network
When Side Tokens are moved back from the other network
