Many projects discuss代付 (payment on behalf), treating it as a kind of benefit: users do not need to prepare gas, and the experience is immediately smooth. However, when you actually run代付, you will quickly realize that it faces two real issues: first, the budget will be consumed much faster than you expect; second, abuse will appear earlier than you imagine. As a result, many teams can only end up creating a 'flash in the pan': free during the event period, tightening after the event ends, leading to a steep decline in user experience. If Plasma wants to create a stablecoin experience as a payment-level foundation,代付 cannot be an event, but must be a long-term operational growth machine—it must lower the threshold to the minimum, keep costs within a controllable range, and finely allocate resources between different groups and scenarios.
I now prefer to understand payment on behalf as a form of 'growth budget.' What you're spending is not gas; you're spending the probability of a user's first successful attempt and their willingness to use it repeatedly. The most valuable aspect of payment on behalf is solving the step where stablecoin users often get stuck: I clearly have stablecoins, but I can't act because I have no gas; I just want to transfer some money, but I'm deterred by a bunch of steps. Once this threshold is removed, the conversion funnel will noticeably shorten, especially when trying to achieve large-scale distribution at the entry level; payment on behalf is almost essential infrastructure. However, because it is so critical, it must be designed as a 'growing' system, rather than a subsidy that will be 'burned out.'
To make payment on behalf sustainable, the first thing is to clarify 'what action you are paying for.' The most worthwhile payments on behalf are always on the critical paths: first transfers, first deposits, first exchanges, first participation in yield entry, and the first payment received by merchants—these actions can bring users into a closed loop. You should not pay for all interactions, nor should you pay for any contract calls. The broader the coverage of payments on behalf, the greater the potential for abuse, making budget control more difficult. The truly mature approach is to narrow the scope of payments on behalf to verifiable business paths, even down to the contract and function level, making payment on behalf a 'part of the product funnel' rather than an open free channel.
The second thing is stratification. The most effective way of payment on behalf is not to distribute evenly to everyone, but to stratify it like the rights system of internet products: new users can enjoy a small amount of 'full payment on behalf' to ensure first success; regular users have a fixed daily or weekly quota, ensuring smoothness without unlimited expansion; high-value users or merchants can have higher quotas, but must bind their contributions and risk control conditions. The essence of stratification is to transform the budget from 'uncontrollable expenditure' into 'predictable cost.' You can even treat payment on behalf as a kind of 'entry gift,' allowing users to first experience the smoothness of stablecoins on Plasma at a low cost, and then gradually transition to more sustainable charges or cost-sharing based on behavior and contributions.
The third thing is to gradually bring heavy users back to the economic system. A truly sustainable payment on behalf system cannot forever pay for everyone. You can transition gently: switch to partial payment on behalf after exceeding limits, or first pay on behalf and then charge a small service fee in stablecoins, or even use a 'payment on behalf to exchange for thresholds' method for certain high-value actions, such as completing binding, verification, or reaching certain asset or behavioral contributions to unlock higher limits. This approach does not weaken the experience but makes it more stable—because only when costs return to the economic system can payment on behalf not suddenly be cut off one day, and users will not experience a cliff-like change.
The fourth thing is to bind risk control with payment on behalf into one entity. The smoother the payment on behalf, the more scripts like it, and the easier it is for real users to be dragged down. You must embed limits, frequency control, anomaly detection, automatic downgrades, and circuit breakers within the payment on behalf system: once an abnormal pattern appears, immediately downgrade the payment on behalf to self-payment or enter a stricter path; in the event of systemic failure or congestion, promptly shrink the scope of payments on behalf to prioritize protection of core paths. Many people mistakenly believe that risk control will harm the experience, but the truth about payment systems is: risk control is the guardian of the experience. Without risk control, payment on behalf will push the system towards instability, ultimately harming all normal users.
Finally, payment on behalf must be reviewable. You need to treat every payment on behalf as a measurable investment: how many first successes did it bring? How much retention improvement did it yield? What is its unit cost of behavior? Which scenarios are the most valuable, and which ones are almost wasteful? When you can answer these questions with data, payment on behalf transforms from 'subsidy' to 'growth model.' And Plasma's narrative will also be more persuasive: it's not because you subsidized more, but because you truly made the stablecoin experience a scalable product.
I want to conclude with a sentence: payment on behalf is not just about helping users pay gas; it is the key lever for stablecoin clearing networks to reach the public. If Plasma wants to achieve long-term network effects, payment on behalf must be an operable, controllable, risk-controllable, and reviewable growth machine. Only in this way can low barriers not become a budget black hole, and smooth experiences not turn into short-term activities.

As I write this, my understanding of Plasma is increasingly approaching a very simple term: basic service. It does not pursue fancy narratives nor relies on short-term stimuli to create a sense of existence; it is more like creating a layer of 'basic services' in the stablecoin era—making stablecoin transfers, settlements, fund management, and potential extensions into payment and credit scenarios more unified, more predictable, and more like financial infrastructure. This route is destined to be slow and more difficult, but once established, its value will be more solid than many fleeting trends.
The reason I make this judgment is that when stablecoins truly reach the public, demand will not start from complex finance but from the most basic actions: transferring, receiving, reconciling, and managing balances. Most people do not want to learn the details of chains; they do not even care 'which chain' it is; they only care 'can I use stablecoins like money.' And what 'like using money' means is encapsulated in four words: certainty. It must go out when sent, the arrival time must be predictable, failures must be clearly explained, and there must be a handling path for problems. These demands may seem ordinary, but for on-chain systems, they are precisely the hardest parts to deliver long-term. By focusing on this main line, Plasma is making the certainty of stablecoins a deliverable service.
Looking further, the real value of the basic service layer lies in unification. One of the biggest problems in today's stablecoin ecosystem is fragmented experiences: different chains have different fee models, different wallets have different pop-ups, and different applications have different authorization logic, requiring users to relearn with each step they take. Fragmentation directly reduces usage frequency, and usage frequency is the root of stablecoin network effects. If Plasma can make the experience more unified—allowing users to get accustomed to using stablecoins for actions without repeatedly adapting to various details—it will resemble a 'default channel' more. Once a default channel is established, users won’t need to make choices, and merchants will find it easier to onboard, as everyone operates within the same set of experiences. This is the strongest source of network effects for infrastructure.
Of course, the basic service layer does not mean 'no challenges.' On the contrary, it faces more realistic challenges: reliability, risk control, error correction, compliance, and scale pressure after entry distribution. The larger the stablecoin user base, the more misoperations and disputes arise, the more abuse and volume inflation occur, and the more the system's jitters are amplified during peak periods. Building a basic service layer means you must incorporate these issues into the design in advance: transaction statuses must be clear and traceable, failure experiences must be recoverable, payments on behalf must be controllable and risk-controllable, disputes and refunds must be procedural, and nodes and RPC must be resilient and fault-tolerant. You will find these things are not sexy, but they determine success or failure; and precisely because they are not sexy, it is easier to create a gap.
If Plasma's route can truly succeed, it will not become 'the hottest narrative,' but it may become 'the most indispensable service.' The winner of the stablecoin era is likely not the one who tells the best stories but the one who can deliver certainty long-term and provide a sufficiently unified experience. If Plasma can continue to deliver on stablecoin clearing and payment-level experiences, it has the chance to grow from 'a project' to one of the candidates for 'the basic service layer of stablecoins.' For me, this is also why I am willing to track Plasma long-term: it is doing what infrastructure should do—slow, but valuable.
