#Chainlink #Keepers and #VRF are live on Fantom! 🎉
#Fantom developers can now utilize VRF for provably random outcomes within their dApps & securely and cost-efficiently automate any smart contract function.
Chainlink Keepers, benefits to developers 🤖
1️⃣ Decentralized Execution — Chainlink Keepers provide reliable, trust-minimized automation with no single point of failure, mitigating risks around manual processes and centralized servers.
2️⃣ Increased Efficiency — Projects that use Chainlink Keepers can reduce time spent on DevOps, minimize operational overhead, and streamline development workflows.
3️⃣ Enhanced Security — Tamper-proof, Sybil-resistant Chainlink Keepers sign on-chain transactions themselves, enabling automated smart contract execution without exposing private keys.
4️⃣ Reduced Costs — Chainlink Keepers perform efficient off-chain computation for smart contracts, allowing developers to build feature-rich dApps at lower costs.
Chainlink VRF, benefits 🎲
1️⃣ Cost-Efficient Randomness Requests — Chainlink VRF includes a subscription management app that lets smart contract applications fund multiple requests for random values using a single token balance managed by the subscription owner.
2️⃣ Variable Callback Gas Limit — Chainlink VRF allows users to adjust the callback gas limit to a 2.5M gas maximum. This enhancement enables smart contracts to execute more sophisticated smart contract logic in the same transaction that delivers verifiable randomness, making the execution of critical tasks involving randomness reliable even during times of network congestion.
3️⃣ Multiple Random Outputs in a Single Request — Chainlink VRF leverages a VRF Coordinator contract that lets users request multiple random numbers in a single transaction. In addition, the fulfillment of randomness is also delivered with a single transaction, lowering costs and reducing response latency.
4️⃣ Subscription Delegation Between Multiple Addresses — Chainlink VRF allows up to 100 smart contract addresses to fund their randomness requests from a single subscription balance managed by the subscription owner. This upgrade saves on gas costs and simplifies funds management for developer teams who operate multiple smart contracts needing verifiable randomness.
“We’re excited to support the Fantom ecosystem with the native integration of Chainlink Keepers and Chainlink VRF. With access to a secure source of automation and randomness, Fantom developers can now develop more advanced hybrid smart contract applications that further drive innovation in the Web3 space.”‒ Sergey Nazarov, Chainlink Co-founder.
