Chainlink has officially launched Payment Abstraction on the Ethereum mainnet. This new feature enables users to pay for Chainlink services in various cryptocurrencies and stablecoins, which are then automatically converted into LINK tokens. The goal is to simplify payment flows and make Chainlink services more accessible.
What’s new
Payment Abstraction is made up of a series of on-chain smart contracts that:
- Accept payments in different tokens across multiple blockchain networks.
- Consolidate these tokens onto a single chain using Chainlink’s Cross-Chain Interoperability Protocol (CCIP).
- Automatically convert the consolidated tokens into LINK via decentralized exchanges (DEXs).
- Route the converted LINK tokens to a dedicated smart contract from which Chainlink network service providers can withdraw them.
The first use case of this system is its integration with Chainlink’s Smart Value Recapture (SVR) — an oracle service that allows DeFi applications to recapture Maximal Extractable Value (MEV) generated through their use of Chainlink data feeds. The fees generated are now automatically converted to LINK and distributed accordingly.
Good to know
The launch of Payment Abstraction significantly streamlines how users and developers interact with Chainlink. There’s no longer a need to hold LINK tokens in advance to pay for services — users can simply use the tokens they already hold. This could drive greater adoption of Chainlink and expand usage of its services.
In the future, Chainlink plans to distribute SVR-generated fees to LINK stakers once the underlying services are secured by Chainlink Staking. This would provide an additional incentive for staking LINK and further enhance the network’s economic sustainability.
