What is the Token Bridge?

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:

Mainnet: tokenbridge.rsk.co
Testnet: testnet.tokenbridge.rsk.co

What is a Side Token (mirror ERC20)?

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.

What is the purpose of having a Side Token?

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.

Will the supply of the original token will increase as a result of Side Tokens?

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.

What is the difference between original tokens and Side Tokens?

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.

What is the Side Token Contract Address, Symbol, and # of Decimal Places in order to add it as a Custom Coin on MyEtherWallet?

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.

How do I transform my original tokens to Side Tokens?

The Token Bridge will be a public DApp where users will be able to access by using Liquality 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 Metamask, you’re also able to transfer the other way around, by sending Side Tokens and receive original tokens.

If I sell my Side Tokens, what happens to my 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.

Is there a limit on how many tokens can be bridged over?

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 is a minimum and maximum amount per transaction and daily quotas. You can see them on https://tokenbridge.rsk.co

Can any token be bridged over?

Only whitelisted tokens can cross the bridge, this curated list is used to avoid malicious contracts and DDoS attacks.

What are the fees for converting original tokens to Side Tokens and vice-versa? Who will be paying these fees?

There is a 0.2% fee charge when crossing the tokens, this fee goes to the validators as payment for crossing the transactions.

How many confirmations are required to convert the original tokens to Side tokens and vice-versa?

Confirmations depends on the amount being crossed:

Small amounts needs 60 confirmations on the RSK Mainnet, and 120 confirmations on the Ethereum Mainnet.
Medium amounts needs 120 confirmations on the RSK Mainnet, and 240 confirmations on the Ethereum Mainnet.
Large amounts needs 2880 confirmations on the RSK Mainnet, and 5760 confirmations on the Ethereum Mainnet.

Note that the values of small, medium, and large amount are defined per token basis,and may change over time.You can see these amounts defined in the Token List.

How does the Token Bridge work?

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

Original tokens are locked in the Token Bridge smart contract
Side Tokens are minted and assigned to the same address that originally called the bridge

When Side Tokens are moved back from the other network

Side Tokens are burned
Original tokens are unlocked in the Token Bridge smart contract, and transfered to the same address that originally called the bridge contract.

FAQs

How long does it take to bridge a token? ›

First you lock your crypto in a smart contract on the blockchain network you're bridging from, and then you'll receive crypto from the network you're bridging to. For example if a user is bridging from Ethereum to Polygon, the first transaction on Ethereum typically takes 10-20min.

What is the block time for rootstock? ›

RSK creates new blocks about every 33 seconds. This is remarkably faster than Bitcoin's 10-minute block time. RSK can also process about 10-20 transactions per second (tps), which is more efficient than Bitcoin's capacity of about 5 transactions per second.

What does bridge token mean? ›

Bridging in crypto refers to the process of transferring assets between different blockchain networks. It aims to enhance interoperability, allowing for data and asset transfers across various networks. The Polygon Bridge is a tool for transferring tokens from the Polygon network to the Ethereum ecosystem.

How old should rootstock be for grafting? ›

Ornamental trees and shrubs: spliced grafts

Scion-wood should be from healthy one- to two-year-old wood. The best rootstocks are two-year-old seedlings, ideally about pencil thickness.

Will rootstock bear fruit? ›

In optimum growing conditions, Standard rootstock trees will bear fruit in 7 to 10 years from planting. These trees are strong, vigorous growers and will produce the highest volume of fruit because of their ultimate size.

What happens if you let rootstock grow? ›

Rootstock Revert: Trees Grafted Return to the Original

If these suckers are not cut off and removed, it can overtake the growth of the graft. The best way to prevent the rootstock from taking over is to remove any new sucker growth that appears below the graft line.

What's the weakest link in the blockchain world? ›

Humans are the Weakest Link in the Blockchain

If a human employee needs to authenticate any transaction or change of custody and enter it into a system, that link is prone to errors or potential fraud. For example, humans with good intentions can simply forget to log a transaction or change of custody.

What happens to your Bitcoin if you use a token-based bridge to make your Bitcoin operable on Ethereum? ›

Cross-chain bridges don't actually move your BTC from the Bitcoin blockchain to the Ethereum blockchain. Instead, the bridge will create equivalent tokens that represent your BTC but are usable on the Ethereum blockchain.
