- Spanish telecommunications giant Telefónica are working together with decentralized oracle provider Chainlink to to combat SIM swapping.
- The partnership will see Telefónica employ Chainlink's connectivity solution Chainlink Functions to securely connect application programmable interfaces (APIs) on GSMA Open Gateway to the Polygon blockchain network.
- The first implementation will use Chainlink Functions in combination with GSMA’s Open Gateway SIM SWAP API to provide additional security for blockchain transactions, allowing smart contracts to query whether a device's SIM card has undergone any unauthorized changes.
- The move positions Telefónica as a "Web3 enabler," said the firm's Chief Metaverse Officer Yaiza Rubio in a press release.
- Last year, Ethereum co-founder Vitalik Buterin fell victim to a SIM swap attack that saw his Twitter profile taken over and used to promote a fake NFT giveaway in which almost $700,000 was stolen from his followers.
