David Schwartz (데이비드 슈워츠), a core designer of the XRP Ledger and former Ripple CTO, acknowledged he wrongly judged early on how digital dollars would be used in the stablecoin industry. On Sept. 15, blockchain outlet U.Today reported that the misjudgment still leads to interface problems that make stablecoin payments inconvenient.

Schwartz explained that developers at the time expected all dollar-pegged stablecoins to use the same USD currency code. He said they believed the ledger did not need to directly support each coin’s ticker and that wallets could display issuer and currency information to match the ticker.

But the market developed differently. As the decentralised finance market became fragmented, major players created their own separate dollar tokens. Users had to keep distinguishing abbreviations such as USDT, USDC and RLUSD rather than making simple transfers. Schwartz said this broke the payment experience familiar to ordinary users.

He proposed splitting the asset display system into two layers as a solution. One would be a global ticker that indicates the nature of the underlying asset, such as the U.S. dollar. The other would be a user-defined ticker that users set directly based on the issuer they trust.

Even for the same dollar, he said each user can decide which issuer’s token to receive. Schwartz said he can receive RLUSD, USDT and USDC all as USD, but other users or companies can set a different range of issuers they trust.

The XRP Ledger has technically addressed part of the problem. Through its trust line mechanism, users can clearly specify which assets they will receive and from which issuer.

In actual payment settings, however, wallet interfaces remain an obstacle. Many cryptocurrency wallets still read only text-based tickers and do not reflect the coin issuer. Schwartz said that until wallets flexibly link issuers and currency codes, stablecoin payments may remain a complex tool for some users rather than naturally replacing fiat currency.

The comments show that a bottleneck in stablecoin adoption may lie in user interfaces rather than asset structure. They also highlighted that even if the XRP Ledger has technical features, payment experiences are unlikely to improve if wallets do not properly reflect them.
