Join the dedicated Builder Chat to ask for feedback and discuss technical questions:Telegram: <a class="link" href="https://t.me/+Xfx2Mx6pbRYxMzA5">https://t.me/+Xfx2Mx6pbRYxMzA5</a><h2 class="heading-node">Context</h2>We want to build a dashboard that will compare quotes and liquidity depth across NEAR Intents and its leading competitors, but first we need to gather the proper data.<h2 class="heading-node">Objective</h2>Adapt <a class="link" href="https://github.com/NEARBuilders/data-provider-playground" target="">this template repository</a> to build an <a class="link" href="https://plugin.everything.dev/" target="">every-plugin</a> plugin that collects and normalizes the desired market data from one of the competitors of NEAR Intents. The various plugins built from this bounty will be compared and aggregated to build our future dashboard.Build a plugin that collects data from one of the below providers (choose exactly one for your submission, you may submit multiple times):<ul class="list-node tight" data-tight="true"><li>LayerZero: <a class="link" href="https://layerzero.network/">https://layerzero.network/</a></li><li>Wormhole: <a class="link" href="https://wormhole.com/">https://wormhole.com/</a></li><li>CCTP: <a class="link" href="https://developers.circle.com/cctp">https://developers.circle.com/cctp</a></li><li>Across: <a class="link" href="https://across.to/">https://across.to/</a></li><li>deBridge: <a class="link" href="https://debridge.com/">https://debridge.com/</a></li><li>Axelar: <a class="link" href="https://www.axelar.network/">https://www.axelar.network/</a></li><li><a class="link" href="http://Li.Fi">Li.Fi</a>: <a class="link" href="https://li.fi/">https://li.fi/</a></li><li>cBridge</li></ul>Metrics required from your chosen provider:<ul class="list-node tight" data-tight="true"><li>Volume</li><li>Rates (Fees)</li><li>Liquidity Depth</li><li>Available Assets</li></ul><blockquote class="block-node">⚠️ ImportantOne submission = one provider.

Avoid on-chain simulation.</li><li>ENV-based configuration for keys, base URLs, and rate limits.</li><li>Resilience: retries with exponential backoff and per-provider rate limiting. A successful plugin must be reliable.</li><li>Documentation: clear README explaining setup, ENV, how to run locally, and how data is derived.</li><li>Sample tests have already been provided <a class="link" href="https://github.com/NEARBuilders/data-provider-playground/tree/main/packages/_plugin_template/src/__tests__" target="">here</a>. A good plugin will enhance these tests, and all tests should pass.</li></ol><h2 class="heading-node">Contract Specification</h2>Each adapter is its own service implementing the same oRPC contract, this is how these plugins work and are composable. You can find the desired contract specification in the template plugin, here: <a class="link" href="https://github.com/NEARBuilders/data-provider-playground/blob/main/packages/_plugin_template/src/contract.ts">https://github.com/NEARBuilders/data-provider-playground/blob/main/packages/_plugin_template/src/contract.ts</a>Contract rules:<ul class="list-node tight" data-tight="true"><li>One repo = one provider. Do not add additional providers in the same codebase.</li><li>Do not change field names or shapes. If you must change names or introduce new fields, let’s discuss in the Telegram Group and document your reasoning.</li><li>Normalize decimals when computing effectiveRate, but keep raw strings for on-chain smallest units.</li><li>LiquidityDepth must at least include thresholds for ≤0.5% and ≤1.0% slippage.</li></ul><hr><h2 class="heading-node">Template Repository</h2>As mentioned, your plugin should be adapted the template repository found here: <a class="link" href="https://github.com/NEARBuilders/data-provider-playground">https://github.com/NEARBuilders/data-provider-playground</a> The repository features a helpful README to get you started, a starter test suite, and an LLM.txt that will help with best practices when working with every-plugin. <a class="link" href="https://github.com/NEARBuilders/data-provider-playground/blob/main/packages/_plugin_template/LLM.txt">https://github.com/NEARBuilders/data-provider-playground/blob/main/packages/_plugin_template/LLM.txt</a><hr><h3 class="heading-node">Budget &amp; Timeline</h3><ul class="list-node"><li>Budget: 800 NEAR<ul class="list-node"><li>100 NEAR per unique competitor data plugin built.</li></ul></li><li>Timeline: Flexible, but preferred delivery within 1-2 weeks</li><li>Payment: lump sum upon successful delivery</li><li>Winner selection: The 8 best solutions (one per competitors) submitted by the deadline of the bounty will be selected 2 days after the bounty deadline.
