How do you handle refunds & chargebacks? And do you have a maximum amount that can be charged?

For context - I'm building a marketplace for artists and struggling to find a global payouts rail. The ones that exist have really high turnover requirements or reject new marketplaces that deal with higher value physical items due to chargeback risk.

Totally get this - one reason I built this was due to the risk of being shut down or rejected from a traditional payment platform. With this there's no risk of being rejected as 1) you can self-host it yourself, and 2) everything is self-custodial on the managed hosting version.

This is mainly for the payout side, but there is a working stablecoin checkout / payments /subscription system in the project - there's no limit on charges, and there are no chargebacks possible because it uses stablecoins.
