On Wednesday, the Stellar Org announced via X that Zipper (Protocol 27) is now live on Mainnet. The protocol upgrade introduces authentication delegation for custom accounts and address-bound smart contract address credentials.
The upgrade introduces SOROBAN_CREDENTIALS_ADDRESS_V2, a new credential type that uses the same signature payload introduced in CAP-0071-01. Unlike the existing address, the new payload explicitly includes the signer’s address, preventing replay attacks between accounts that share private keys when the invocation payload does not otherwise bind the signer address.
The protocol also adds a first-class protocol mechanism for custom (smart contract) accounts to delegate their authentication logic to other addresses.
Stellar is an open-source network with the mission to "create equitable access to the global financial system." Stellar is maintained by the Stellar Development Foundation, a non-profit organization established in 2014.
The Stellar network is a decentralized, fast, scalable, and uniquely sustainable blockchain built for financial products and services. The network launched in 2014 with the purpose of connecting the world's financial systems by offering a protocol for payment providers and financial institutions that facilitates near-instant global payments and currency exchanges. In 2024, Stellar released protocol 20, enabling full-featured smart contracts to the network. The network is transforming international payments and remittances through safer, faster, and more affordable solutions, and connecting real-world assets to DeFi to enable comprehensive everyday financial services.
The Stellar network’s native digital currency - Lumens (“XLM”) - is used to pay the network’s transaction fees. (XLM can also be used as an intermediate currency for operations. How it works: the protocol converts money in a few seconds, first into XLM, and then into the requested currency.)
XLM is down 0.7% in the last 24 hours and now trades at $0.1811 per coin.
