Rewards Bridge Layer
🌉 What is the Reward Bridge?
The Reward Bridge is the part of Idle Network that connects off-chain infrastructure rewards with on-chain yield strategies.
It handles the automatic transfer of rewards from external platforms (like GLM, HNT, RENDER) and forthcoming native rewards networks into Idle’s MetaVaults on Base. You don’t need to manually bridge or swap anything. Idle does it all behind the scenes using adapters and secure bridge contracts.
Think of it as your invisible yield pipeline: from mining → to bridging → to vault → to compounding.
🌐 Supported Chains & Adapters
Each rewards network operates on its own chain or reward system. Idle supports these using custom adapters built for each protocol.

Each adapter:
Monitors your node rewards
Claims tokens when thresholds are met
Sends them through the Reward Bridge to Base
As new rewards networks are added, Idle will plug in new adapters to expand reward coverage.
🚀 How Rewards Are Moved to Base
Once the rewards are claimed, they’re moved to Base using the following flow:
Collection: Idle’s adapter contract claims rewards from the protocol or your wallet.
Swap (Optional): In some cases, tokens are first swapped into a bridgeable token (e.g. ETH, USDC).
Bridge: The tokens are sent through secure bridges (like KyberSwap and Mayan Protocol)
Deposit to Meta-Vault: Once on Base, the tokens are routed into the Meta-Vault and reinvested.
Idle’s system keeps track of your rewards through the entire journey. You’ll see all movements reflected in your dashboard with no manual actions required.
🛡️ Bridge Security
Bridging is one of the most sensitive parts of any DeFi system. Idle’s Reward Bridge follows strict security standards:
Audited Bridges: Idle only uses trusted bridge providers with battle-tested contracts and large TVLs.
Rate Limits: Idle enforces per-user and per-token limits to prevent abuse or draining attacks.
Dual-Signature Claims: In some protocols, rewards are only claimed after verifying your desktop node’s proof + wallet signature.
Retry Queues: If a reward claim or transfer fails, the system queues it for retry, not loss.
Additionally, Idle separates the bridging logic from vault logic. That means any bug or attack in the bridge can’t directly drain funds from the Meta-Vaults.
🔁 Fallback Mechanisms
What if the bridge is down or a network is slow?
Idle uses fallback tools to make sure rewards still get through:
Multiple Bridges: If one bridge is congested, Idle routes through an alternate.
Delayed Processing: If rewards can’t be sent in real-time, they’re stored securely and batched later.
Manual Reclaim: Advanced users can always trigger a manual claim via the Idle dashboard or desktop app.
No matter what happens your rewards won’t get stuck or lost. Idle is built to reliably move value from physical devices to yield strategies, with built-in recovery paths if anything goes wrong.
