track_changes Relay

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.

repeat Autotasks

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.
flare Sentinels

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.

repeat Advisor

Quickly implement security best practices

Protocol complexity is increasing, leading to new vulnerabilities that you might not be aware of. Use Defender Advisor knowledge-base to stay up to date with the latest security best practices. Use step-by-step guides to implement them across development, testing, monitoring and operations.
