This guide details how XLM holders can provide liquidity to the KSM/XLM pool on Zenlink DEX via the Amplitude network on Kusama. It covers setting up a Polkadot wallet, acquiring KSM and AMPE, bridging XLM using Spacewalk from Lobstr, and adding liquidity. The process enables earning rewards while enhancing liquidity in the Amplitude ecosystem.
Pendulum's Q1 2024 roundup highlights the launch of the Spacewalk bridge connecting Stellar and Polkadot ecosystems for seamless XLM and stablecoin transfers. Key developments include reward structures for bridge vaults, new liquidity pools on Zenlink and StellaSwap, and progress on Forex AMM powered by Nabla. Community engagement and governance updates further strengthen the ecosystem's growth.
A protocol on Stellar has deployed an airdrop of its governance token to early and super adopters, distributing 28.8 million out of 64 million total supply via claimable balances. Claim deadline is April 30, 2024, with unclaimed tokens returning to the DAO treasury. Future protocol fees will fund the DAO for community governance.
The Spacewalk Bridge is now live on the Pendulum network, enabling trust-minimized transfers of XLM and fiat-backed stablecoins like EURC, AUDD, NGNC, TZS, and BRL between Stellar and Polkadot ecosystems. Stellar users can trade XLM on Zenlink DEX and provide liquidity in pools such as XLM.s/PEN and XLM.s/DOT. Pendulum's Forex DEX powered by Nabla offers single-sided liquidity provision without impermanent loss, enhancing DeFi accessibility.
A comprehensive guide explaining authentication and authorization mechanisms in blockchain, with specific focus on how Stellar and Soroban implement these security features through digital signatures, multisig, thresholds, and smart contract-based account abstraction.
Stellar network validators voted to upgrade Mainnet to Protocol 20 on Feb. 20, enabling Soroban smart contracts with a phased rollout approach. The upgrade delivers a secure, scalable, and developer-friendly smart contract platform built on Rust and WASM, designed for real-world financial inclusion and low-cost transactions.
The Stellar Development Foundation has decided to disarm its validators and postpone the Protocol 20 upgrade scheduled for January 30, 2024, following ecosystem concerns about a discovered bug in Stellar Core v20.1.0 affecting fee bumps for Soroban transactions.
The Stellar Development Foundation disclosed a bug in Stellar Core v20.1.0 affecting fee-bumped Soroban transactions, where refunds are incorrectly sent to the sponsored account instead of the sponsor. SDF decided to proceed with the Protocol 20 upgrade vote on January 30 as planned, citing low risk during early Soroban phases and the availability of mitigation best practices.
Aquarius announces updates and 2024 plans for building AMMs on Stellar using Soroban smart contracts. They've developed CPMM and StableSwap models inspired by Uniswap and Curve, with AQUA rewards for liquidity providers. A new UI and integrations are planned post-Soroban mainnet launch on January 30, 2024.
Stellar's Protocol 20 upgrade, which enables Soroban smart contracts on Mainnet, is approaching a validator vote. The upgrade implements 12 Core Advancement Proposals and unlocks new possibilities for developers while maintaining Stellar's existing capabilities.
