Bitcoin's smart-contract-enabled sidechain RSK is introducing the concept of meta-transactions, which allow tertiary parties to pay for a user's transaction fees.

Appear on Th, the "RIF Enveloping" solution enables wallet providers to pay for their users' transactions. Paying transaction fees is currently a major bottleneck in the adoption of smart contract platforms. Users wishing to trade tokens must e'er have some units of the blockchain's native currency — for example, Ether (ETH) for Ethereum and Smart Bitcoin (RBTC) for RSK.

RIF Enveloping introduces meta-transactions to enable greater flexibility for decentralized application developers. Smart contracts using the technology can choose to subsidize the user'due south gas fee completely or request payment with tokens. The applied science will be integrated with Beexo Wallet, 1 of the chief wallet providers for RSK.

Like solutions be on Ethereum as well, using OpenZeppelin'due south Gas Station Network. Wallets that use information technology include Argent, which uses smart contracts to store the user'southward tokens. While the company used to subsidize gas costs completely, the skyrocketing prices on Ethereum led them to discontinue the program. Nonetheless, despite their apparent benefits, meta-transactions have yet to achieve meaning adoption on Ethereum.

Diego Gutierrez Zaldivar, co-founder of RSK, told Cointelegraph that RIF Enveloping tin exist more than impactful to RSK's ecosystem:

"One of the primary reasons why RIF Enveloping can accept broader adoption than like solutions in the Ethereum ecosystem is that the solution was jointly designed with wallet providers such as Beexo, Defiant, Coin on Chain, RSK Swap and large communities of users similar Taringa, to maximize efficiency."

He also explained that RSK's solution has a technological advantage. Meta-transactions on Ethereum crave redeploying contracts or using proxies, while RIF Enveloping can work with any existing token or contract.

RSK features a growing ecosystem for decentralized finance. The recent launch of Sovryn brought a full suite of trading and lending products, while existing platforms like Money on Concatenation or RSK Bandy recreated core DeFi projects on Ethereum similar MakerDAO or Uniswap.
