Stackup company
Overview
Stackup is a Los Angeles-based crypto finance company that today markets itself as a digital asset management platform for crypto companies, providing crypto finance infrastructure so businesses can get paid onchain, automate bill payments and grow revenue. Its feature set covers payment acceptance and optimisation through invoices, subscriptions and payment tracking; vendor payments made online or via API; treasury unification across crypto and traditional banking; and enterprise-grade financial controls and compliance reporting. Under the hood it uses ERC-4337 smart accounts, with consumer-grade security features such as Face ID authentication - a direct continuation of Stackup's origins as an account abstraction infrastructure provider. The product is live at app.stackup.fi with documentation at docs.stackup.fi and a trust portal at trust.stackup.fi, and the site carries a 2025 copyright, indicating active operation. Note that the company's original domain, stackup.sh, now permanently redirects to stackup.fi, reflecting the shift in positioning from developer bundler infrastructure to crypto business finance. Stackup started as an ERC-4337 account abstraction infrastructure provider and has repositioned as a digital asset management and payments platform for crypto businesses, moving its web presence from stackup.sh to stackup.fi while continuing to build on ERC-4337 smart accounts. Its customers include the protocol auditing firm Cantina.
