@0xPolygon CEO @0xMarcB went public this week with a pointed complaint about his team's experience working with the Stripe-backed payments blockchain Tempo, saying the integration process had stalled for nearly a month over a single unmerged pull request.
Writing on social media, Boiron said he had "waited almost a month for the @tempo team to merge a PR so that we can integrate Trails with Tempo and offer their users and our customers a better cross-chain experience." He also said he had attempted to contact Tempo's core team members directly, without success, describing those outreach efforts as having gone unanswered.
The stalled work centres on Trails, Polygon's intent-powered cross-chain orchestration product. Trails forms part of Polygon's broader payments stack, sitting alongside the AggLayer for unified liquidity and the Polygon CDK for launching compliant connected blockchains. Completing the integration would have allowed Tempo's users and Polygon's customers to access improved cross-chain functionality across both networks.
The frustration is notable given the profile of both parties. Boiron joined Polygon Labs in 2022 as Chief Legal Officer and became CEO the following year, steering the ecosystem towards becoming a leading payments-focused blockchain while developing an internet of interoperable blockchains via the AggLayer. On the other side, Tempo raised $500 million at a $5 billion valuation in 2025 from investors including Joshua Kushner's Thrive Capital, and went live on mainnet on March 18, 2026, after a public testnet phase that began in December 2025.
After Boiron's post gained attention, @liamihorne, described as a member of Tempo's core team, replied publicly within minutes. The speed of that response stood in sharp contrast to the weeks of silence Boiron said his team had encountered through private channels, and the exchange quickly drew scrutiny from the wider crypto developer community.
The episode highlights a tension that can arise when high-profile projects in adjacent ecosystems attempt to collaborate. Cross-chain interoperability remains a central challenge in Web3, with a secure way to move value between different chains still largely missing from the ecosystem. Both Polygon and Tempo are working to address that gap, making smooth collaboration between the two networks arguably in both parties' interest.
Boiron has not indicated whether the pull request has since been merged or whether the integration is back on track.
