Build with private and secure transaction infrastructure
Don’t spend time implementing third-party or homegrown transaction infrastructure that is unreliable or insecure. Use Defender Relay to quickly implement private relayers with support for testnets, mainnet, layer 2 and sidechains. Increase user security with embedded key vaults, API key management, and meta-transactions.
repeatAutotasks
Create automated scripts to call your smart contracts
Homegrown bots and cron jobs are tedious to maintain and a target for hackers. With Defender Autotasks, you can easily create and run scripts in a serverless environment that call your smart contracts and other web services. Automate your operations and lower attack risk.
flareSentinels
Monitor and respond to smart contract exploits
Use Defender Sentinels to automatically monitor and respond to events, functions, and transaction parameters on your smart contracts. With full Autotask integration, you can add circuit breakers or automated actions so your team can respond to attacks within seconds and receive notifications via email, Slack, Telegram, or Discord.
