first_img Moody's and Chainlink complete pilot project for cross-chain distribution of credit ratings

According to Decrypt, Chainlink and Moody's Ratings have completed a pilot project demonstrating how to simultaneously distribute credit ratings across multiple blockchains. The test was announced on Tuesday, using Chainlink's cross-chain interoperability protocol CCIP to distribute Moody's ratings to both permissioned and permissionless chain networks.The pilot operates through Moody's Ratings Token Integration Engine TIE, which was built by the 125-year-old rating agency to disseminate credit assessments and related data in a blockchain environment. Both parties stated that the pilot proves that ratings can be transmitted across chains through a single interoperability layer while retaining Moody's existing publishing and governance processes. Moody's has rated or assessed over 70 digital issuances, including digital bonds and tokenized funds, from January 2017 to October 2026.Johann Eid, Chief Business Officer of Chainlink Labs, stated that as more financial assets go on-chain, credit intelligence must flow cross-chain and accompany every rating change. Fabian Astic, Global Head of Digital Economy at Moody's, believes that the future of tokenized finance is unlikely to exist solely on a single blockchain, platform, or market infrastructure.This pilot runs entirely on a testnet using representative test data and has not published any actual rating actions on-chain; it is a proof of concept rather than a live product. Previously, Moody's launched TIE on the institutional-grade Canton Network and subsequently expanded to Solana.

first_img The vulnerability bounty platform Immunefi has launched Credits, and over 700 researchers have received allocations

The blockchain vulnerability bounty platform Immunefi announced the launch of Immunefi Credits. Since the submission fee mechanism was initiated, researchers will receive an equivalent amount of Credits for effective reports, covering valid discoveries, valid reports of duplicate submissions, privately known issues, and situations where the mediation results are favorable to the researchers. The platform stated that over 700 researchers have already received Credits without needing to apply separately, and the amount can be viewed on the Credits page associated with the console balance.Immunefi stated that starting today, Credits can be used to pay for submission reports, mediation, account verification, and other fees within the platform, and will be used for related services once Immunefi Studio is open to the public. One Credit is worth 1 US dollar and can be purchased with USDC. Credits do not replace vulnerability bounties or audit competition rewards; valid discoveries will still receive rewards according to the original rules, and additionally receive Credits equivalent to the submission fees. The Credits issued retroactively will be valid for 12 months from today, and thereafter each Credit will be valid for 12 months from the date of crediting, bound to the account, and non-transferable or redeemable.Eligible situations also include valid discoveries already paid in vulnerability bounties or confirmed in audit competitions, duplicates of valid reports by others, privately known issues and their duplicates, as well as mediation fees when mediation is won. Publicly known issues, invalid reports, out-of-scope submissions, policy violations, duplicates of rejected reports, and duplicates of self-reports are not counted. Account verification fees can earn equivalent Credits when there is a valid report after verification and the accuracy rate reaches at least 25%. The fee mechanism has been applicable to vulnerability bounties since March 24 and to audit competitions since April 10, with relevant verifications currently conducted approximately every two weeks.

first_img OpenAI grants free API credits to ChatGPT Pro and Business

OpenAI documentation shows that eligible ChatGPT Pro and Business subscriptions can receive free API credits for building applications and agents within their own API organization. The credits are automatically issued based on the subscription, and any unused portion expires at the end of the billing cycle without carrying over; when there are valid free credits, there is no need to bind an API payment method. In terms of monthly credits, Pro's tiers of $100, $200, and $500 correspond to $100, $200, and $500 respectively; Business Standard provides $20 per paid seat, and Business Premium provides $100 per paid seat.The initial issuance is calculated proportionally based on the remaining time in the current subscription billing cycle and expires at the end of that cycle. Business API credits are shared within the workspace, with a monthly cap of $500; annual payment workspaces receive a one-time issuance of the annual credits, which expire at the end of the annual billing cycle. Users must log in to ChatGPT with an eligible subscription account, with Pro credits claimed in Settings under Billing, and Business credits claimed in the workspace billing settings or Admin Console, confirming the API organization receiving the credits.The credits cover the paid usage of associated organizations on the API Platform, including Responses API, Agents API, Decisions API, GPT-Live and Realtime API, Images API, as well as built-in tools and related costs such as web search, document search, and Code Interpreter. Using Codex via API key is not included in the benefits, and the credits will not increase the usage limits for ChatGPT or Codex that is already logged in. Free credits are prioritized over purchased credits; when exhausted and no remaining credits are available, requests will fail with HTTP 429 and error code credit_balance_exhausted.
